冷轧板带用途很广，如汽车制造、电气产品、机车车辆、航空、精密仪表、食品罐头等。 　　冷轧薄钢板是普通碳素结构钢冷轧板的简称，也称冷轧板，俗称冷板，有时会被误写成冷扎板。冷板是由普通碳素结构钢热轧钢带，经过进一步冷轧制成厚度小于4mm的钢板。由于在常温下轧制，不产生氧化铁皮，因此，冷板表面质量好，尺寸精度高，再加之退火处理，其机械性能和工艺性能都优于热轧薄钢板，在许多领域里，特别是家电制造领域，已逐渐用它取代热轧薄钢板。 　　适用牌号：Q195、Q215、Q235、Q275；SPCC（日本牌号）；ST12（德国牌号） 　　符号：冷轧板的用途 　　1、Q—普通碳素结构钢屈服点（极限）的代号，它是“屈”的第一个汉语拼音字母的大小写；195、215、235、255、275—分别表示它们屈服点（极限）的数值，单位：兆帕MPa（N/mm2）；由于Q235钢的强度、塑性、韧性和焊接性等综合机械性能在普通碳素结构钢中属最了，能较好地满足一般的使用要求，所以应用范围十分广泛。 　　2、S-钢（Steel）、P-板（Plate）、C-冷轧（cold）、第四位C-普通级（common）。 　　3、ST-钢（Steel）、12-普通级冷轧薄钢板、　 　　标记：尺寸精度—尺寸—钢板品种标准 　　冷轧钢板：钢号—技术条件标准 　　标记示例：B-0.57501500-GB708-88；钢板、标准号Q/BQB402，牌号SPCC，热处理状态退火+平整（S），表央加工状态为麻面D，表面质量为FB级的切边（切边EC，不切边EM）钢板、厚度0.5mm，B级精度，宽度1000mm，A级精度，长度2000mm，A级精度，不平度精度为PF.A，则标记为：钢板ECQ/BQB 402-SPCC-SD-FB/（0.51000A2000A-PF.A）； 　　冷轧钢板：Q225-GB912-89 　　主要产地有：宝钢、鞍钢、本钢、武钢、邯钢、包钢、唐钢、涟钢、济钢等 　　冷轧普通薄钢板 ：由普通碳素结构钢或低合金结构钢冷轧制成。冷轧板表面质量较好。具有良好的冲压性能。对其要求要保证冷弯和杯试验合格，常用于汽车等行业和镀层板的原料。 　　冷轧优质薄钢板：主要包括各种优质钢冷轧薄板，最常用的是碳素结构钢板，尤其是深冲压用冷轧薄钢板，是由低碳优质钢08Al冷轧的薄板，钢板按表面质量分为三组；Ⅰ、Ⅱ、Ⅲ，分别表示特别高级、高级、较高的精整表面,按拉延级别分为ZF、HF、F级（代表用于冲制拉延最复杂、很复杂、复杂的零件）,根据钢板厚度允许偏差，又分为A、B两级精度、广泛用于汽车拖拉机工业。 　　冷轧钢板，表面光洁，加工优良，用于汽车、冰箱、洗衣机等家电，以及产业设备、各种建筑材料。随着经济发展，冷轧钢板已被称为现代社会的必须材料。 冷轧产品的分类： 热轧酸洗、轧硬卷、普通冷轧、镀锌（电镀锌、耐指纹、热镀锌）、镀铝锌、电镀锡、彩涂、电工钢（矽钢片）等。 　　1、热轧酸洗：　　2、轧 硬 卷：在常温下，对热轧酸洗卷进行连续轧制。　　产品特点：因为没有经过退火处理，其硬度很高（HRB大于90），机械加工性能极差，只能进行简单的有方向性的小于90度的折弯加工（垂直于卷取方向）。

冷轧是在室温条件下将钢板进一步轧薄至为目标厚度的钢板。和热轧钢板比较，冷轧钢板厚度更加精确，而且表面光滑、漂亮，同时还具有各种优越的机械性能，特别是加工性能方面。因为冷轧原卷比较脆硬，不太适合加工，所以通常情况下冷轧钢板要求经过退火、酸洗及表面平整之后才交给客户。冷轧最小厚度是0.1--8.0MM以下，大部份工厂如保定普瑞钢材冷轧钢板厚度是4.5MM以下；最少厚度、宽度是根据各工厂的设备能力和 市场 需求而决定。冷轧的优缺点：优点：成型速度快、 产量 高，且不损伤涂层，可以做成多种多样的截面形式，以适应使用条件的需要；冷轧可以使钢材产生很大的塑性变形，从而提高了钢材的屈服点。缺点: 1.虽然成型过程中没有经过热态塑性压缩，但截面内仍然存在残余应力，对钢材整体和局部屈曲的特性必然产生影响；2.冷轧型钢样式一般为开口截面，使得截面的自由扭转刚度较低。在受弯时容易出现扭转，受压时容易出现弯扭屈曲，抗扭性能较差；3.冷轧成型钢壁厚较小，在板件衔接的转角处又没有加厚，承受局部性的集中荷载的能力弱。镀锌是在装有镀件、玻璃球、锌粉、水和促进剂的旋转滚桶内，作为冲击介质的玻璃球随着滚桶转动，与镀件表面发生摩擦和锤击产生机械物理能量，在化学促进剂的作用下，将镀涂的锌粉“冷焊”到镀件表面上，形成光滑、均匀和细致的具有一定厚度的镀层。镀锌分为热镀锌和电镀锌两种。热镀锌也叫热浸镀锌和热浸锌，是一种有效的 金属 防腐方式，主要用于各 行业 的 金属 结构设施上。是将除锈后的钢件浸入500℃左右融化的锌液中，使钢构件表面附着锌层，从而起到防腐的目的。电镀锌，是利用电解设备将管件经过除油、酸洗、后放入成分为锌盐的溶液中，并连接电解设备的负极，在管件的对面放置锌版，连接在电解设备的正极接通电源，利用电流从正极向负极的定向移动就会在管件上沉积一层锌，冷镀管件是先加工后镀锌。

冷轧：用热轧钢卷为原料，经酸洗去除氧化皮后进行冷连轧，其成品为轧硬卷，由于连续冷变形引起的冷作硬化使轧硬卷的强度、硬度上升、韧塑指标下降，因此冲压性能将恶化，只能用于简单变形的零件。轧硬卷可作为热镀锌厂的原料，因为热镀锌机组均设置有退火线。轧硬卷重一般在6~13.5吨，钢卷在常温下，对热轧酸洗卷进行连续轧制。内径为610mm。产品特点因为没有经过退火处理，其硬度很高（HRB大于90），机械加工性能极差，只能进行简单的有方向性的小于90度的折弯加工（垂直于卷取方向）。简单来说，冷轧，是在热软板扎的基础上加工轧制出来的，一般来讲是热轧→酸洗→冷轧这样的加工过程。冷轧是在常温状态下由热轧板加工而成，虽然在加工过程因为轧制也会使钢板升温，尽管如此还是叫冷轧。由热轧经过连续冷变形而成的冷轧，机械性能比较差，硬度太高，必须经过退火才能恢复其机械性能，没有退火的叫轧硬卷。轧硬卷一般是用来做无需折弯，拉伸的产品，1.0以下厚度轧硬的运气好的两边或者四边折弯。化学成分（Wt%）牌号CSiMnPSCuSPCC0.02～0.08≤0.100.15～0.30≤0.045≤0.050≤0.050Q1950.06～0.12≤0.300.25～0.50≤0.045≤0.050≤0.050Q235-B0.12～0.20≤0.300.30～0.70≤0.045≤0.050≤0.050制作工序冷轧通常采用众轧的方式。冷轧生产的工序一般包括原料准备、酸洗、轧制、脱脂、退火(热处理)、精整等。冷轧以热轧产品为原料，冷轧前原料要先除磷，以保证冷轧产品的表面洁净。轧制是使材料变形的主要工序。脱脂的目的在于去除轧制时附在轧材上的润滑油脂，以免退火时污染钢材表面，对不锈钢也为防止增碳。退火包括中间退火和成品热处理，中间退火是通过再结晶消除冷变形时产生的加工硬化，以恢复材料的塑性及降低金属的变形抗力。成品热处理的目的除了通过再结晶消除硬化外。还在于根据产品的技术要求以获得所需要的组织(如各种织构等)和产品性能(如深冲、电磁性能等)。精整包括检查、剪切、矫直(平整)、打印、分类包装等内容。冷轧产品有很高的包装要求，以防止产品在运输过程中表面被刮伤。除上述工序外在生产一些特殊产品时还有各自的特殊工序。如轧制硅钢板时，在冷轧前要进行脱碳退火，轧后要进行涂膜、高温退火、拉伸矫直(见张力矫直)与回火等。用于冷轧带刚的轧机有二辊轧机、四辊轧机和多辊轧机。应用最多的是四辊轧机。轧制更薄的产品则要采用多辊轧机。多辊轧机的种类很多，如六辊轧机、偏八辊轧机，十二辊轧机，二十辊轧机等(见轧机)。随着对板形要求的提高，发展了许多改进板形的技术，如弯辊技术、窜辊技术和交叉轧辊技术等。冷轧带钢轧机按机架排列可分为单机可逆或不可逆式与多机连续式两类。前者适用于多品种、少批量或合金钢产品比例大的情况。它投资低、建厂快，但产量低，金属消耗较大。多机架连续轧制适合于产品品种较单一或者变动不大的情况，它有生产效率高、产量大的优点，但投资较大。与热轧带钢(见热连轧宽带钢生产工艺、热轧窄带钢生产)相比，冷轧带钢(见冷板扎带生产)的轧制工艺有以下特点：(1)采用工艺润滑和冷却，以降低轧制时的变形抗力和冷却轧辊；(2)采用大张力轧制，以降低变形抗力和保持轧制过程的稳定。采用的平均单位张力值为材料屈服强度的10%～60%，一般不超过50%；(3)采用多轧程轧制。由于冷轧使材料产生加工硬化，当总变形量达到60%～80%时，继续变形就变得很困难。为此要进行中间退火，使材料软化后轧制得以继续进行。为了得到要求的薄带钢，这样的中间退火可能要进行多次。两次中间退火之间的轧制称为一个轧程。冷轧带钢的退火在有保护气体的连续式退火炉或罩式退火炉中进行(见冷轧板带退火)。冷轧带钢的最小厚度目前可达到0.05mm，冷轧箔材可达到0.001mm。

冷轧钢板就是经过冷轧生产的钢板，俗称冷板。　　冷轧是在室温条件下将No.1钢板进一步轧薄至为目标厚度的钢板。和热轧钢板比较，冷轧钢板厚度更加精确，而且表面光滑、漂亮，同时还具有各种优越的机械性能，特别是加工性能方面。因为冷轧原卷比较脆硬，不太适合加工，所以通常情况下冷轧钢板要求经过退火、酸洗及表面平整之后才交给客户。冷轧最大厚度是0.1--8.0MM以下，如大部份工厂冷轧钢板厚度是4.5MM以下；最少厚度、宽度是根据各工厂的设备能力和市场需求而决定。 　　一般来说，冷轧钢板分为三代产品：沸腾钢为第一代，铝镇静钢为第二代，无间隙原子刚（IF钢）为第三代。   您查询的关键词是：冷轧钢板  。如果打开速度慢，可以尝试快速版；如果想保存快照，可以添加到搜藏。 "冷轧钢板""2,冷轧钢板(YB459-64)""厚度(mm)","宽度和长度 (mm)","理论重量(kg/m2)(比重:8.9)",,"厚度(mm)","宽度和长度 (mm)","理论重量(kg/m2)(比重:8.9)""0.4","600x1200 700x1430 800x1500 1000x2000","3.56",,"2.5","6000x1200 7000x1430 800x1500 1000x2000","22.25""0.45",,"4.01",,"2.75",,"24.48""0.5",,"4.45",,"3.0",,"26.70""0.6",,"5.34",,"3.5",,"31.50""0.7",,"6.23",,"4.0",,"35.60""0.8",,"7.12",,"4.5",,"40.05""0.9",,"8.01",,"5.0",,"44.50""1.0",,"8.90",,"5.5",,"48.95""1.1",,"9.79",,"6.0",,"53.40""1.2",,"10.68",,"6.5",,"57.85""1.35",,"12.02",,"7.0",,"62.30""1.5",,"13.35",,"7.5",,"66.75""1.65",,"14.60",,"8.0",,"71.20""1.8",,"16.02",,"9.0",,"80.10""2.0",,"17.80",,"10.0",,"89.00""2.25",,"20.03""冷轧铜条""2,冷轧铜条(YB459-64)""厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.9)",,"厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.9)""0.20","200~400","500~800","1.78",,"2.50","200~500","500~2000","22.25""0.25",,,"2.23",,"2.75",,,"24.48""0.30",,,"2.67",,"3.00",,"1000~2000","26.70""0.35",,,"3.12",,"3.50",,,"31.15""0.40","200~500","500~2000","3.56",,"4.00",,,"35.60""0.45",,,"4.01",,"4.50",,,"40.05""0.50",,,"4.45",,"5.00",,,"44.50""0.60",,,"5.34",,"5.50",,,"48.95""0.70",,,"6.23",,"6.00",,,"53.40""0.80",,,"7.12",,"6.50",,,"57.85""0.90",,,"8.01",,"7.00",,,"62.30""1.00",,,"8.90",,"8.00",,,"71.20""1.20",,,"10.68",,"9.00",,,"80.10""1.30",,,"11.57",,"10.00",,,"89.00""1.40",,,"12.46",,"11.00",,,"97.90""1.50",,,"13.35",,"12.00",,,"106.8""1.60",,,"14.69",,"13.00",,,"115.7""1.80",,,"16.02",,"14.00",,,"124.6""2.00",,,"17.80",,"15.00",,,"133.5""注 铜板和条(热轧,冷轧)的制造牌号为T2,T3,T4和TU和TUP,其化学成分应符合YB145-71规定""特殊用冷轧黄铜条""3,特殊用冷轧黄铜条(YB555-65)""厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.8)",,"厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.8)""0.20","200~300","500~1000","1.76",,"1.6","200~500","500~2000","14.08""0.25",,,"2.20",,"1.8",,,"15.84""0.30","200~400",,"2.64",,"2.0",,,"17.60""0.35",,,"3.08",,"2.5",,,"22.00""0.40","200~500",,"3.52",,"2.75",,,"24.20""0.45",,,"3.96",,"3.0",,,"26.40""0.50",,"500~2000","4.40",,"3.5",,,"30.80""0.55",,,"4.84",,"4.0",,,"35.20""0.60",,,"5.28",,"4.5",,,"39.60""0.70",,,"6.16",,"5.0",,,"44.00""0.80",,,"7.04",,"5.5",,,"48.40""0.90",,,"7.92",,"6.0",,,"52.80""1.0",,,"8.8",,"6.5",,,"57.20""1.2",,,"10.56",,"7.0",,,"61.60""1.3",,,"11.44",,"8.0",,,"70.40""1.4",,,"12.32",,"9.0",,,"79.20""1.5",,,"13.20",,"10.0",,,"88.00""注 (1)标记举例:用H80制成的,厚度为0.8mm,宽度为300mm,长度为1000mm的1/2硬条标记为:"" 条H80-Y20.8x300x1000YB555-65.""

冷轧：用热轧钢卷为原料，经酸洗去除氧化皮后进行冷连轧，其成品为轧硬卷，由于连续冷变形引起的冷作硬化使轧硬卷的强度、硬度上升、韧塑指标下降，因此冲压性能将恶化，只能用于简单变形的零件。轧硬卷可作为热镀锌厂的原料，因为热镀锌机组均设置有退火线。轧硬卷重一般在20-40吨，钢卷在常温下，对热轧酸洗卷进行连续轧制。内径为610mm。　　　　产品特点：因为没有经过退火处理，其硬度很高（HRB大于90），机械加工性能极差，只能进行简单的有方向性的小于90度的折弯加工（垂直于卷取方向）。　　　　简单来说，冷轧，是在热轧板卷的基础上加工轧制出来的，一般来讲是热轧---酸洗---冷轧这样的加工过程。　　　　冷轧是在常温状态下由热轧板加工而成，虽然在加工过程因为轧制也会使钢板升温，尽管如此还是叫冷轧。由于热轧经过连续冷变型而成的冷轧，在机械性能比较差，硬度太高。必须经过退火才能恢复其机械性能，没有退火的叫轧硬卷。轧硬卷一般是用来做无需折弯，拉伸的产品，1.0以下厚度轧硬的运气好的两边或者四边折弯。　　　　冷轧一般都会经过退火处理。

冷轧薄钢板，简称冷轧钢板、冷轧薄板、冷轧板、冷板等。它还包括不锈钢板、弹簧钢板、硬钢片、镀锌板、镀锡板、镀铝板等。冷轧薄钢带，简称冷轧钢带、冷轧带钢、钢带、带钢、薄钢带、冷轧卷等。还包括不锈钢带、镀锌钢带、镀锡钢带等。 冷轧钢板标准 冷轧薄钢板、钢带（以下简称冷轧薄板）主要用于零件的冲压加工，而冷轧薄板的力学性能十分重要，它直接关系到板材的冲压性能。冷轧薄板是以不同的热处理状态分级的，不同硬度的材料，用于不同的加工方法，国家标准GB/T 13237-1991《优质碳素结构钢冷轧薄钢板和钢带》将冷轧薄板大致分为三级，P级用于普通冲压，S级用于深度冲压，Z级用于最深度冲压。中国冶金标准YB/T 5059-1993《低碳钢冷轧钢带》将薄钢板按硬度分为五级，即：TR（特级）、R（软）、BR（半软）、DY（低硬）和Y（冷硬）。其实通过一定的冷轧变形程度和冷轧后热处理的恰当配合，可以在广泛的范围内满足用户关于材料力学性能方面的要求。冷轧薄板根据用户加工上的要求可以分成更多的级别。例如：日本工业标准JIS G3141-1996《冷轧碳素钢钢板和钢带》的分类除分为一般用（spcc）、冲压用(spcd)和深冲压用（spce）三类外，还细分为退火、标准调质、1/8硬、1/4硬、1/2硬、全硬等级别。 在冷轧薄板力学性能的检测方面，一些标准只规定了拉伸试验，另一些标准除拉伸试验外还规定了硬度试验。 中国标准GB/T 13237-1991就只规定了拉伸试验，技术要求冷轧钢板标准如表一所示：牌号 抗拉强度/MPa伸长率不小于拉延级别Z－S和PZSP08F275～365275～38034323008,08Al,10F275～390275～41032302810295～410295～43030392815F315～430315～45029282715335～450335～47027262520355～490335～50026252425——390～540——242330——440～590——222135——490～635——201940——510～650————1845——530～680————1650——540～715————14 日本标准JIS G3141-1996《冷轧碳素钢钢板和钢带》（该标准中包含了冷轧薄钢板和钢带）规定了拉伸试验，也规定了硬度试验，该标准的力学性能要求如下：表二：标准调质和退火的钢板、钢带的拉伸试验质牌号抗拉强度/MPa 不小于 伸长率/%不小于试样按以下公称厚度/mm>=0.250.250.400.601.01.6>=2.5SPCC SPCD SPCE(270) 270 270(32) 34 36(34) 36 3836 38 40　 37 39 41 　　 (38) 40 42 　39 41 435号试样轧制方向 表三：标准调质和退火的钢板、钢带的硬度值。调质区分符号 硬度最大HRBHV退火A57105标准调质S65115 注：厚度小于0.6mm的钢板和钢带，原则上不进行拉伸试验。 表四：1/8硬、1/4硬、1/2硬和全硬材料的拉伸试验值。调质区分 符号 抗拉强度/MPa伸长率/%最小试样1/8硬8294～410255号试样轧制方向1/4硬4370～490101/2硬2440～590——硬1>=550——     表五：1/8硬、1/4硬、1/2硬和全硬状态的硬度值。调质区分符号HRBHV1/8硬 1/4硬8450～7165～8095～130 115～1501/2硬 硬2174～89 ≥85135～185 ≥170注：HRB和HV，仅选用其中之一。英国标准BS 1449/1.9-1991《厚板、薄板和钢带第一部分：碳素钢和碳锰钢厚板、薄板和钢带具有成形性能的冷轧窄钢带技术条件》对冷轧板分级为CS1（铝镇静稳定化超深冲）、CS2（超深冲）、CS3（深冲）、CS4（折边）、CS15（商品级）。这项标准的力学性能要求如表六所示： 表六：钢材交货时的力学性能轧制状态和级别退火（A）或平整冷轧（SP）状态硬度HV1)2)最大屈服强度Re1)/MPa最小抗拉强度Rm1)/MPa最小伸长率A1)/%最小弯心直径1)（180°弯曲）原始标距LO50mm80mmCS1A9514027038（36）0aSP10514027036（34）0aCS2A9514027036（34）0a SP10014027036（34）0aCS3A100（140）（280）（34）（32）0aSP110（140）（280）（34）（32）0aCS4A105（140）（280）——0aSP115（140）（280）——0a 注：1）窄钢带交货应符合，或者硬度和弯曲试验，或者拉伸和弯曲试验，但硬度和拉伸试验不应同时进行。     2）对于SP（平整冷轧）状态，与镀层精整（PL）或镜面光洁度（MF），或以“无拉伸痕”交货的钢材组合，最大硬度可以提高5个HV或抗拉强度可以提高20MPa。     3）牌号CS2、CS3和CS4的硬度值仅适用于沸腾钢。 如上所述冷轧薄板的力学性能可以通过拉伸试验来检测，也可以通过硬度试验来检测。由于硬度试验设备简单、易于掌握，试验效率高，并且金属硬度与强度之间有一定的对应关系，所以硬度检测是确定材料力学性能的更方便的方法。冷轧薄板的硬度检测可以用于冷轧板生产过程的质量控制，更适于生产冲压产品的厂家对原材料进行力学性能的复检。 日本工业标准JIS G3141-1996规定的硬度试验是洛氏硬度HRB和维氏硬度HV。维氏硬度试验可用于冷轧薄板，但洛氏硬度HRB却不适用于测试薄板材料。因为当板材厚度小于2mm时，测试HRB硬度可能会因为发生“测砧效应”而使测量的硬度值失准。对于薄板材料，可以测试表面洛氏硬度HRN或HRT，然后换算成HRB或HV硬度。冷轧钢板标准生产了一种便携式表面洛氏硬度计，它非常适合测试薄板和钢带材料，它可以在生产现场、销售现场或材料仓库快速进行冷轧薄板材料的洛氏硬度检测，完成一次测量仅需要10秒钟时间，检测的板材厚度范围为0.05-50mm。这种仪器可以用在冷轧薄板带的生产线上，对产品的热处理效果进行在线的质量控制。这种仪器更适用于冲压产品的生产厂家。可以用它对购入的板材硬度进行复检，可以携带它去钢材市场选购材料，也可以利用它对自己厂生产的冲压产品进行硬度检测。 这种仪器如果配上一个支承座，还可以放到办公桌上使用。可以对成批的成品或半成品工件做逐件检测。它的测试精度与台式洛氏硬度计相同。 目前冷轧薄带材料正在向超薄方向发展，据报道，上海宝钢已扎制出厚度为0.08mm的冷轧薄板带材。采用本所生产的PHR-1S型表面洛氏硬度计，配一个金刚点砧座，就可测试薄至0.05mm冷轧薄板带材料的硬度。 这种应用完全可以取代维氏硬度计，使冷轧薄板材料的力学性能检测实现快速、简便、经济。

冷轧镀锌板，是一种镀锌钢板。钢板按轧制分为热轧和冷轧两种。冷轧板是平板状的，矩形的，可直接轧制而成的。冷轧是在室温条件下将钢板进一步轧薄至为目标厚度的钢板。和热轧钢板比较，冷轧钢板厚度更加精确，而且表面光滑、漂亮，同时还具有各种优越的机械性能，特别是加工性能方面。因为冷轧原卷比较脆硬，不太适合加工，所以通常情况下冷轧钢板要求经过退火、酸洗及表面平整之后才交给客户。冷轧最小厚度是0.1--8.0MM以下，大部份工厂如保定普瑞钢材冷轧钢板厚度是4.5MM以下；最少厚度、宽度是根据各工厂的设备能力和 市场 需求而决定。冷轧和热轧的区别： 1、冷轧成型钢允许截面出现局部屈曲，从而可以充分利用杆件屈曲后的承载力；而热轧型钢不允许截面发生局部屈曲。2、热轧型钢和冷轧型钢残余应力产生的原因不同，所以截面上的分布也有很大差异。冷弯薄壁型钢截面上的残余应力分布是弯曲型的，而热扎型钢或焊接型钢截面上残余应力分布是薄膜型。3、热轧型钢的自由扭转刚度比冷轧型钢高，所以热轧型钢的抗扭性能要优于冷轧型钢。冷轧的优缺点：优点：成型速度快、 产量 高，且不损伤涂层，可以做成多种多样的截面形式，以适应使用条件的需要；冷轧可以使钢材产生很大的塑性变形，从而提高了钢材的屈服点。缺点: 1.虽然成型过程中没有经过热态塑性压缩，但截面内仍然存在残余应力，对钢材整体和局部屈曲的特性必然产生影响；2.冷轧型钢样式一般为开口截面，使得截面的自由扭转刚度较低。在受弯时容易出现扭转，受压时容易出现弯扭屈曲，抗扭性能较差；3.冷轧成型钢壁厚较小，在板件衔接的转角处又没有加厚，承受局部性的集中荷载的能力弱。冷轧镀锌板用于汽车、冰箱、洗衣机等家电，以及 产业 设备、各种建筑材料。

冷轧钢板就是经过冷轧生产的钢板。冷轧是在室温条件下将No.1钢板进一步轧薄至为目标厚度的钢板。和热轧钢板比较，冷轧钢板厚度更加精确，而且表面光滑、漂亮，同时还具有各种优越的机械性能，特别是加工性能方面。因为冷轧原卷比较脆硬，冷轧钢板的密度不太适合加工，所以通常情况下冷轧钢板要求经过退火、酸洗及表面平整之后才交给客户。冷轧最大厚度是0.1--8.0MM以下，如大部份工厂冷轧钢板厚度是4.5MM以下；最少厚度、宽度是根据各工厂的设备能力和市场需求而决定。冷轧钢板的密度：热轧钢板含碳量可比冷轧钢板略高些。在成份相持不大的情况下密度是一样的。但如果成份相差悬殊，如不锈钢不论冷轧、热轧密度都在7.9g/cm3左右。具体还要看成份，热轧只是延展性更好，钢材同样受到压力作用

（二）电工用冷轧硅钢薄板（GB2521-88）  　　用含硅0.8％-4.8％的电工硅钢为材质，经冷轧而成。  　　冷轧硅钢片分晶粒无取向和晶粒取向两种钢带。冷轧电工钢带具有表面平整、厚度均匀、叠装系数高、冲片性好等特点，且比热轧电工钢带磁感高、铁损低。用冷带代替热轧带制造电机或变压器，其重量和体积可减少0％-25％。若用冷轧取向带，性能更佳，用它代替热轧带或低档次冷轧带，可减少变压器电能消耗量45％-50％，且变压器工作性能更可靠。  　　用于制造电机和变压器。通常，晶粒无取向冷轧带用作电机或焊接变压器等的状态；晶粒取向冷轧带用作电源变压器、脉冲变压器和磁放大器等的铁芯。  　　钢板规格尺寸：厚度为0.35、0.50、0.65mm，宽度为800-1000mm，长度为≤2.0m。

二者的首要差异在于涂漆的阶段和工艺不同。 　　预滚涂是在基材仍是卷状时，在流水线上经过酸洗、矫相等程序，依据要求的漆层厚度，有电脑操控，经过几烤几烘，在相对密闭的空间内完结。滚涂后就是一卷卷带漆层的铝板。如使用时依据尺度直接裁剪和折弯，即可施工。     喷涂是在依据施工图纸断定的规格，对不带漆层的铝板裁剪和折弯成型后，再用喷上漆。     关于商场上的金属铝幕墙来说，种类许多。就涂漆层面来说，首要分喷涂、预滚涂及电镀等。综合功能比较，是喷涂远低于预滚涂，预滚涂在部分指标上低于电镀;在空间上，国产首要是喷涂，国外已是预滚涂产品占主流了，电镀产品在国外也早有人用了。国内和国外为何会形成这种“代”差呢?首要原因有以下二个方面：     资金、技能和设备。     国内幕墙厂商多，规划小，鱼龙混杂，不乏作坊式出产。关于数十亿美元一条的滚涂出产线和严厉的技能配套要求来说，明显还不具备条件。     建筑理念和商场观念要素等。也就是人祸。建筑是千秋大业仅仅嘴上说说罢了，我们只管眼前利益而不讲久远效益。(一个比如是上海陆家嘴的一楼盘，十几如果平方的价格外墙仅用铝塑板贴了拉倒，降低成本啊，成果成交廖廖)。业主外行，出产商就都拼报价，偷工减料，压低薪酬，献身质量，技能研制和升级换代就更是无稽之谈了，成果就是整个职业留步不前。     1***H**——指含99%纯铝的纯铝板     2***H**——指铝铜合金     3***H**——指铝锰合金     4***H**——铝硅合金     5***H**——铝镁合金，可用做船板或防弹铝板.     H1*——静态煺火(也叫最终煺火);     H2*——动态煺火(继续出产线上煺火，也叫中间煺火);     H3*——内部应力处理;     H4*——上面三种只需涂层后都是4.     H*2、H*4、H*6——后边的数字是硬度比值。数字越小，硬度越小;反之越大。     普基铝镁板是预滚涂板，不是喷涂板AA5754H44基材，2.0mm厚度的产品各项功能已卓而不群,选用接连三涂三烤工艺，抗老化、不掉漆，涂层氟碳树脂含量达70%以上,加强筋选用镀锌钢板，柔性衔接，强度高，不变形。删去

镀锌格栅板，即格栅板生产出来以后，要进行防锈处理。有热镀锌（热浸镀锌）和电镀锌（冷镀锌）2种。格栅板是钢格板的别名，是用扁钢按照一定的间距和横杆进行交叉排列，并且焊接成中间带有方形格子的一种钢铁制品，主要用来做水沟盖板，钢结构平台板，钢梯的踏步板等．横杆一般采用经过扭绞的方钢作为一种新材料、新产品正得到日益广泛的应用，其较多的优越性能及良好的性能 价格 比显示了其应用的前景。格栅板的制作方式：有机器压焊和手工制作两种.机器压焊使用高压电阻压焊机,机械手自动将横杆横放在均匀排列的扁钢上,通过强大的电焊功率和液压力将横杆压焊入扁钢内,从而可以得到焊点坚固,稳定性和强度极高的高品质格栅板.手工制作的格栅板是先在扁钢上冲孔,然后将横杆放入孔中点焊,横杆与扁钢会存在空隙,而且不可能每个接触点都进行焊接,因此焊接不牢固,强度有所降低. 　　在冶金、矿山、石油、电力与工业领域以及一些民用领域中，格栅板作为一种新型建材正得到日益广泛的应用。所谓新材料，其实在国外已有几十年以上的历史，不过在中国得到广泛应用也只是近１０年的事。但就象铝合金门窗一样，与传统材料相比，人们习惯上还是将其称作新材料。格栅板特点及用途特点： 1.高强度，轻结构：牢固的网格压焊结构使其具有高承载，结构轻2.便于吊装等特点3.外形美观，经久耐用：热浸锌表面处理使其具有相当好的防腐能力4.表面光泽美观5.通风、采光、散热、防爆、防滑性能好；防积污物用途：广泛应用于石油化工、电厂、水厂、污水处理厂、市政工程、环卫工程等领域的平台、走道、栈桥、沟盖、井盖、梯子、围栏、护栏等。  

将镍及镍合金板经熔炼、铸锭、平辊轧制加工成单张或成卷加工材的过程。镍及镍合金具有熔点高、热稳定性好、耐蚀、强度高、加工性能良好等优点。镍合金板带材广泛用于精密仪表、电子、医疗器械、航天航空等工业部门。热轧板厚度5～20mm，冷轧板厚度0．5～10mm，宽度不大于1000mm；带材厚度0．05～1．5mm，宽度一般不大于300mm。镍及镍合金板带的基本生产工艺流程如下：熔铸 镍及镍合金板熔体能吸收大量气体，发生强烈的氧化。一般采用感应电炉熔炼、熔体表面覆盖玻璃，用木炭、锰、硅、镁、钛等脱氧。高纯度的镍及镍合金板采用真空熔炼。蒙乃尔(NCu28—2．5—1．5)等合金采用电渣熔炼。熔炼温度在1450～1560℃之间，随合金而异。通常扁锭用生铁模铸造(见生铁模铸锭)或半连续铸造(见半连续铸锭)。锭重在30～400kg范围内。铸锭表面的夹杂、冷隔等缺陷应进行清理.热轧 镍及镍合金板的高温塑性良好，变形抗力较高，加热温度在1050～1250℃范围内，以电炉加热为宜。若使用煤气炉，则煤气含硫量必须严格控制，以免造成热脆。重400kg厚度为200mm的镍锭，经11个道次热轧至10mm厚。有时热轧前先行锻造，以改善内部组织.酸洗 镍及镍合金板铣面(见有色金属合金锭坯铣面)时易粘刀具，故对热轧板坯常用酸洗的方法除去表层的氧化物。酸洗采用硫酸与硝酸的混合酸，或单独的硝酸。为提高酸洗效果，酸洗前先以小压下量冷轧一道，使延伸小于基体的氧化层被破碎，以利于同酸反应.冷轧 厚度5．0～13．5mm的热轧坯，需经多次反复冷轧和退火，到达成品厚度。两次退火间的压下率可达70％～85％。冷轧常用四辊轧机。高强度的镍合金薄带采用12辊或20辊轧机精轧。冷轧时应充分润滑和冷却，以防粘辊，影响表面质量.退火 退火分中间退火和成品退火。中间退火的目的是消除冷轧造成的加工硬化；成品退火则为了控制成品性能。镍和镍合金板完全退火的温度在570～850IC间，取决于合金成分和制品厚度。成卷薄带退火时易于粘结，故退火前应重卷。因镍合金板的氧化皮较难清除，故常用钟罩式真空炉进行退火。镍铝、镍钛和其他复杂镍合金板可通过固溶／时效处理实现沉淀硬化，以提高强度. 

硅钙板又称石膏复合板，是一种多孔材料，具有良好的隔音、隔热性能，在室内空气潮湿的情况下能吸引空气中水分子、空气干燥时，又能释放水分子，可以适当调节室内干、湿度、增加舒适感。石膏制品又是特级防火材料，在火焰中能产生吸热反应，同时，释放出水分子阻止火势蔓延，而且不会分解产生任何有毒的、侵蚀性的、令人窒息的气体，也不会产生任何助燃物或烟气。硅钙板主要由石膏组成,由硅质材料（硅藻土、膨润土、石英粉等）、钙质材料、增强纤维等作为主要原料，经过制浆、成坯、蒸养、表面砂光等工序而制成的轻质板材。简介：硅钙板吊顶主要优点是质轻、防水、吸声，施工简单。一、材料要求高强硅钙板（600X600X15）、3m长ψ8镀锌吊杆，16X22“T”型铝合金次龙骨、16X28“T”型铝合金主龙骨、12X18“L”形铝合金边龙骨二、主要机具电锯、无齿锯、手电锯、冲击电锤、电动螺丝刀、手刨、钳子、扳手、水准仪、靠尺、钢卷尺三、施工条件和相关环境墙身四周弹好吊顶的+50cm水平标高控制线，并核查完毕。安装完顶棚内的各种管线及通风道，确定好灯位、通风口及各种露明孔口位置。并核对吊顶高度与其内设备标高是否影响。检查所用的材料和配件是否准备齐全。在上龙骨之前必须完成墙面地面的湿作业项目。搭设好顶棚施工的操作平台架子。硅钙板龙骨吊顶在大面积施工前，应做样板间，对顶棚的起拱度、灯槽、通风口的构造处理，分块及固定方法等应经试装并经鉴定后可大面积施工。四、施工工艺弹标高水平线、划龙骨分档线-固定吊挂件-安装边龙骨-安装主龙骨-安装次龙骨-罩面板安装

镀锌楼层板，一种镀锌产品，其基材就是楼层板。在楼层板成型后，通过热镀锌或电镀锌工艺，在其表面镀上一层锌，达到防腐蚀的目的。楼层板是采用镀锌钢板经辊压冷弯成型，其截面成V型、U型、梯形或类似这几种形状的波形，主要用作永久性模板，也可被选为其他用途。镀锌楼层板广泛用于电厂、电力设备公司、汽车展厅、钢结构厂房、水泥库房、钢结构办公室、机场候机楼、火车站、体育场馆、音乐厅、大剧院、大型超市、物流中心、奥运场馆体育场馆等钢结构建筑。镀锌楼层板的特点：1、易于安装施工, 节省工时. 2、取代传统模板, 善传统模板需耗时拆木板模之缺点. 3、可作为结构强度之一部份. 4、易于配筋, 配线, 配之施工. 5外观整齐美观, 改善传统施工的杂乱无章。

热镀锌格栅板，又称热镀锌钢格板，是用扁钢按照一定的间距和横杆进行交叉排列，并且焊接成中间带有方形格子的一种钢铁制品，主要用来做水沟盖板，钢结构平台板，钢梯的踏步板等。横杆一般采用经过扭绞的方钢作为一种新材料、新产品正得到日益广泛的应用，其较多的优越性能及良好的性能 价格 比显示了其应用的前景。热镀锌格栅板一般采用碳钢制作，外表热镀锌，可以起到防止氧化的作用，也可以采用不锈钢制作。格栅板具有通风，采光，散热，防滑，防爆等性能。格栅板的分类： 　　按焊接方式，可分为：压焊型、相嵌型、穿锁型和穿焊型。 　　按按其负载扁钢侧表面的形状，可分为：平面型、齿型和“工”字型等。 　　按其用途可分为：一般用途钢格栅板和专门用途的钢格栅板如：地沟盖板、踏步板等等。 　　按材料分为：不锈钢钢格栅板和碳钢钢格栅板。热镀锌格栅板的特点：高强度，轻结构；防腐能力强，经久耐用；外形美观，表面亮泽；便于安装他折卸；通风，采光，散热，防滑，防爆性好；不积污物，不积雨雪，不积水，自清洁，易于维护。热镀锌格栅板的应用：广泛应用于石油化工，电力，自来水，污水处理，港口码头，建筑修饰，造船，自走式停车场，市政工程，环卫工程等领域平台，走道，栈桥，沟盖，井盖，梯子，围栏等。 　　格栅板的制作方式：有机器压焊和手工制作两种。机器压焊使用高压电阻压焊机，机械手自动将横杆横放在均匀排列的扁钢上，通过强大的电焊功率和液压力将横杆压焊入扁钢内，从而可以得到焊点坚固,稳定性和强度极高的高品质格栅板，手工制作的格栅板是先在扁钢上冲孔,然后将横杆放入孔中点焊，横杆与扁钢会存在空隙，而且不可能每个接触点都进行焊接,因此焊接不牢固,强度有所降低。 　　在冶金、矿山、石油、电力与工业领域以及一些民用领域中，热镀锌格栅板作为一种新型建材正得到日益广泛的应用。所谓新材料，其实在国外已有几十年以上的历史，不过在中国得到广泛应用也只是近10年的事。所以热镀锌格栅板在中国 市场 的前景良好。

钢栅板，又称钢格板，所以镀锌钢栅板就是镀锌钢格板。镀锌钢格板，是指表面镀有一层锌的钢格板。钢格板是用扁钢按照一定的间距和横杆（扭绞方钢、方钢、圆钢、扁钢等）进行交叉排列，并且焊接成中间带有方形格子的一种钢铁制品，钢格板主要用来做水沟盖板，钢结构平台板，钢梯的踏步板等．横杆一般采用经过扭绞的方钢．钢格板一般采用碳钢制作，外表热镀锌，可以起到防止氧化的作用。也可以采用不锈钢制作．钢格板具有通风，采光，散热，防滑，防爆等性能。钢格板表面处理方式：热镀锌、冷镀锌、喷漆、浸防锈油、不处理。钢格板的特点外形美观：线条简捷。银色外表，现代潮流。最佳排水：漏水面积达83.3%，是铸铁的两倍多。热浸镀锌：防锈力强，免维护及更换。防盗设计：盖与框用铰联接，防盗，安全，开启方便。节省投资：大跨。重载时，比铸铁价低且节省被盗话压碎更换的费用。 　　高强度：强度和韧性远高于铸铁，可用于码头，机场等大跨度和重载荷的环境。 　　镀锌钢栅板的应用适用于合金，建材，电站，锅炉，造船，石化，化工及一般工厂房、市政建设等 行业 ；用于城市道路，广场，园林，码头，机场，停车场，公路，铁路，工业工程等各类工业民用建筑。 

废铝 走势 对于现在的 金属市场 来说有一定的前景， 市场 内人士分析，对于 有色金属 来说，即便是废铝 走势 ，在 市场 内未来的几年中仍然应该被看好。近日中美经济数据打压 金属 需求前景，沪铝跟随整个 金属市场 走跌，抑制 现货 铝报价，而随着 现货 铝价的走跌，本周各地废铝 走势 报价均有所下滑，环比下跌 100元左右，受铝市调整， 市场交易 气氛淡静，持货商与下游收购商心态分歧，同时临近交割，商家恐慌 价格 会进一步下跌，故持币观望， 市场 清淡无人问津，虽然铝市需求仍未有明显的改善，铝价反弹高度有限，但出于对后市看好，持货商在跌价时依然较为惜售，而部分贸易商也有意抄底囤货搏升，对铝价形成一定支持。预计废铝 走势价格 依然保持平稳。一般而言，废铝 走势 都以 市场 价为主，变动情况较大，根据不同的废铝 走势市场行情 来进行适当的涨跌。以下是一些近期废铝 走势价格 报价：响铜 64000 花线 55600 进口亮铜 54700 国产亮铜 54300 紫铜 52000 电机线 50500 天津低氧杆 56300  H62（熟黄） 37600 H65 20000  磁性黄铜94 40000 六六三 46500大件黄铜 37000 黄件 34600 机铝 12400 易拉罐 12000 铝合金 13500 铝线（拔丝带钢芯）15600 废铝线 14300 活塞（机体） 13500 汽车轮毂 13800 （单位：元/吨）以下是昨日的广东清远废铝 价格 报价：机件生铝(Fe 3%) 12750-12950；机件生铝(Fe6%-8%) 11850-12050；变压器铝(94-95%) 12350-12500；港装压块唛仔(含杂≤4%) 10050-10150。由此数据显示，废铝 走势 跌幅大于 现货 铝锭。主要因在跌价时，废铝 走势价格 表现抗跌，而在涨价时，废铝 走势价格 同样表现滞涨，致使两者价差进一步的扩大，由月初的1500附近再度拉大至1800，这使得废铝 走势 变得相对超值，有助于增强下游厂家对废铝的采购意欲，从而对废铝 走势 形成支持。

10.06.24，在美联储货币政策会议后公布声明前，镍走势市场人士各种臆测均有，市场处在相对“真空”之空隙，尤其在盘初，有部分基金的少量买盘追逐稍前欧元兑美元转强的态势，大幅拉抬基本金属的铜和镍金属的价格，引发基本金属的整体涨势。这种基金行为是不能单纯用供需基本面可以解释的。不能不考虑这是基金考虑战略撤出前的“虚步骤”，料高度有限。有一个判断的依据是，近来油价的攀升得益于投资者对经济将快速复苏的预期，但目前看联储的预期并没有这样乐观。基本金属前期的表现亦是建立在对经济将快速复苏的预期。事实是，LME的基本金属市场收市之后，美联储货币政策会议后公布的声明，并没有新意，反倒是基金的少量买盘激发了市场在前期基金逐步出货后的跌势中反弹。　　10.06.25，基本金属（包括期镍）的走势继美联储在周三LME收市之后就储货币政策会议后公布的表态声明中得到了暗示：短期内不会升息。但经济仍将保持疲弱一段时间。尽管期铜以及期镍等基本金属因美国国内生产总值(GDP)萎缩幅度的数据小于预期，但在原油上涨的指引下，带动市场短线看多的气氛，并盖过了疲弱就业数据的影响，使得部分看空者无奈以技术性手法回补空头部位，但对经济仍有不安情绪。10.06.26，基本金属中铜等多头将本周涨势获利了结。但镍金属异军突起，继续保持涨势，这主要是期镍金属的部分看空者无奈跟涨所致，也就是说，这种技术性回补买盘通常是由暴露了空头部位的看空者一种技术性自救行为所产生。期镍盘中曾一度由高点回落。10.06.29，美8月原油合约上涨2.33美元，收于71.49美元/桶，创下两周来新高，涨幅为3.4%。原本疲弱的美元，在油价的大幅上涨下，盘中反弹，致使基本金属铜等金属（包括期镍）的多空频繁换手。由于存在对即将到来的第三季度的期待，投资者亦在重新分配投资组合。但明显看出，对第三季度经济复苏的持续性存有疑虑者亦不在少数。短期也仅仅是由于第二季度即将结束，一些基金机构想维持本身在第二季度的收益率，而积极参与了原本已经在高位品种的炒作。综合镍走势看，仍维持对镍金属市场短期触顶的判断，短期“M头”态势的迹象初露端倪。短期在美元下行走势下，将支持镍金属价格，在没有引发大量的空翻多之前，即便期镍短线有所上行，空间也非常有限，仍维持震荡回落是主基调观点。

锡价走势对于锡来说很重要，锡作为一种重要的金属，其走势自然也是我们十分关心的一个内容。锡是我国的优势矿种,研究并掌握其价格走势、市场动态,对于制定产业发展战略,安排矿山生产具有重要的现实意义.利用统计资料,在系统分析国际锡价格百年走势、资源分布情况以及锡的产量与消费量形势的基础上,对锡市场前景进行了预测,认为未来几年世界锡的消费量仍将有较大的增长潜力,国际锡价格将有回升的余地.接下来是一篇08年的文章，我们可以看出如果掌握其走势，对我们研究很有帮助。经过上半年度的不断攀升、创新高的锡原材料市场行情来看，下半年度价格应会再创新高！原因如下：1、全球金属市场特别是锡市场的需求量增加。如：美国、日本、欧洲是锡的消耗大国。供给方面：从全球角度看，下半年锡产量比上半年预计有所增加，但各国政策的风险以及生产的不稳定对供应的威胁始终存在。印尼政府陆续发放12家企业的出口和生产许可证，此轮对锡生产行业的调整基本结束，相关政策也已经出台。预计下半年印尼的产量会有所恢复，但我们认为很难恢复到整顿前的水平，产量的增加将是有限的。其他的主要产锡国，东南亚的马来西亚、泰国的冶炼产能对印尼出口的粗锡存在一定的依赖性，因此，印尼的矿业整顿将影响两国的锡产量。南美地区除巴西的Paranapanema 矿山外，其他矿山的产量都在减少；澳大利亚的锡产量也一直处于减少之中；而玻利维亚由于国有化之后，一直面对着与嘉能可公司的法律纠纷，其产品不能正常销售；秘鲁国内Minsur 独家经营，产量相对稳定；另外，刚果产量尽管有所增加，但总量很小，而且政府限制资源外流，出口存在障碍。中国下半年的锡产量仍会有所增加，但预计国家政策和环保压力将导致增速放缓。需求方面：07年全球的锡需求保持增长，供需缺口与2006 年相比将继续放大。上半年全球需求尽管没有达到预期的增速，但考虑中国经济的持续强劲，以及美国、日本、欧洲等高GDP地区（传统的锡需求大国）经济转强的预期，预计下半年锡需求增速有望加快。2、今年通货膨涨，人民币升值，调高矿产业税制等大环境影响带动锡市场的上涨。国内因素：今年国内市场物价狂升已成为事实，不论民生用品还是工业用品都是上涨势头，带动锡市场上涨。再因8月1日起矿石资源税最高调整幅度可达1500%!增矿产业运营成本。3、看回国内市场，如其深圳本地市场，生产旺季很快将到，锡需求将大大增加。4、市场存在炒作行为，掌握走牛信号，持货者继续坚持惜售，市场供应偏紧，造成供求关系失调。5、市场关于价格的传闻太多（有15万、有16万/吨），制造货紧气氛。掌握锡价走势可以说就能帮你预测未来，上海有色网中有你所需要的锡价走势内容，你可以登陆上海有色网锡专区查看。

阳极氧化(anodic oxidation)，是将金属或合金的制件作为阳极，选用电解的方法使其表面构成氧化物薄膜。金属氧化物薄膜改变了表面状况和功能，提高了其耐腐蚀性、增强耐磨才能及硬度，然后维护金属表面。　　怎样区别阳极氧化　　1、阳极氧化抗静电，电表红黑南北极轻压铝板表面，指针读数很小甚至为0，仿冒品指针有读数，表明表面导电，且读数跳动不定，表明表面漆膜不均匀；　　2、阳极氧化表面后，密度很厚，不吸尘不沾油烟，重复接触后不会留有手印；　　3、其他防品在外观上和进口板十分类似，可是细心区别，可发现那些材料表面缺少金属光泽，摸起来较粗糙，材料发白；　　铝合金阳极氧化板材对铝基材的要求很高，作为阳极氧化铝的铝材的纯度要求适当高。当然，纯度越高的铝材报价就越高，这也是阳极氧化铝报价高的原因之一。所以，市道有许多的阳极氧化铝，顾客要注意辨认其真伪。怎样辨别其真伪呢？关于一般的顾客来说，有一个简单易行的方法，就是看原料表面是否有金属质感，真实的阳极氧化铝的氧化膜看上去、摸上去都是同金属自身构成一体的，没有人工覆上去的感觉。

        铜锡合金板具有优良的耐弯性，柔韧性，节省空间性，信号高速传输性及抗电磁干扰性，可用于笔记本，手机，液晶屏等电子设备的内部布线，彩色超声波诊断装置用探测传输线等产品。极细同轴电缆有进一步细径化的需求，要实现极细同轴电缆的细径化，要求导体材料本身具有高导电性和可承受反复弯曲及扭转的高强度特性。　　众所周知，锡铅(SN-PB)合金焊料能优异，在电子元器件的组装领域得广泛应用。但是，非常遗憾的是SN-PB中的铅对于环境和人体健康有害，限制使用含铅电子材料的活动已正式启动。 也因此很多国家都开始励行削减铅使用量的活动。在这样的背景下，强烈要求开发无铅焊接技术和相应的锡铜SN-CU合金电镀技术。   无铅焊料电镀技术要求　　关于无铅焊料电镀层和电解液，除了不允许使用含铅物质之外比较难于实现的是要求与以往一直使用的SN-PB电镀层有同样的宝贵特性。具体要求的性能，如下所述：(1)环境安全性——不允许有像铅PB等有害人体健康和污染环境的物质；(2)析出稳定性——获得均匀的外表面和均匀的合金比例；(3)焊料润湿性——当进行耐热试验和高温、高湿试验后，焊料的润湿性仅允许有很小程度的劣化；（4）抑制 金属 须晶产生；(5)焊接强度粘着性——同焊料材料之间接合可靠性；（6）柔韧性——不发生断裂；（7）不污染流焊槽;（8）低成本；(9)良好的可作业性——主要是指电解容易管理；(10)长期可靠性——即使是长期使用电解液，也能保证电镀层稳定；(11)排水处理——不加特殊的螯合剂(CHELATE)，可利用中和凝聚沉淀处理方法清除重 金属 。　　在选择无铅焊料电镀技术时，应当综合分析权衡上述诸多因素，选SN-PB电镀性能的无铅焊料电镀技术，选择SN-CU（合金焊料）电解液的原因作为无铅焊料电镀技术，现已研究很多种，诸如，试图以SN-ZN、SN-BI、SB-AG和SN-CU电镀取代一直使用的SN-PB电镀。然而，这些无铅电镀技术也是各有短、长，并非十全十美。例如，SN电镀的优点是低成本，确有电子元器采用电镀锡的力方法，因为是单一 金属 锡，当然不存在电镀合金比率的管理问题。可是，SN电镀的缺点突出，如像产生 金属 须晶(WHISKER)而且焊料润湿性随时间推移发生劣化。SN-ZN电镀的长处于在成本和熔点低，美中不足是大气中焊接困难，必须在氮气中实现焊接。SN-BI电镀的优势是熔点低而且焊料润湿性优良，其劣势也不胜枚举：因为BI是脆性 金属 ，含有BI的SN-BI镀层容易发生裂纹，而且组装后的器件引线和电路板焊接界面剥（LIFTOFF），更麻烦的是电解液中的BI3+离子在SN-BI合金阳极或电镀层上置换沉积。SN-AG电镀的优点是接合强度以及耐热疲劳特性都非常好，缺点是成本高，也存在SN-AG阳极和SN-AG镀层上出现AG置换沉积现象。　　上述的无铅电镀技术都有优异的特性，同时也存在很多有待进一步研究的课题，实用化为时尚早。为此，日本上村工业公司认为SN-CU电镀最有希望取代SN-PB电镀，可以发展成实用化技术，于是决定开发SN-CU电解液。关于SN-CU电镀层特性，它除了熔点稍许偏高(SN-CU共晶温度227℃)之外，润湿性良好。成本低，对流焊槽无污染，而且可抑制 金属 须晶生成。　　SN-CU合金焊料的开发SN/SN2+的标准电极电位是-0．136VVS．SHE(25℃)，然而CU/CU2+是+0．33V，两者之间的电位差比较大，在—般的单纯盐类电解液里，铜CU很容易优先析出。　　而且，当用可溶性SN阳极或者SN-CU合金阳极的时候，由于电解液中的CU2+离子和阳极的SN之间置换反应产生析出沉表1标准电解液和作业条件(获得SN-LWT%CU镀层的情况积。因此，把电解液中的SN2+和CU2+的析出电位搞得相接近，需要有抑制铜CU优析出的络合剂。通过研究各种各样的络合剂，最后终于找到SN-CU电解液配方，它能使SN和CU形成合金并可抑制在铜CU阳极上的置换沉积。       现在使用铜锡合金板已经不是什么不可能实现的问题了。在电子元器件的组装领域得广泛应用。 

今日硅钙板价格各地区小幅下调，成交价格混乱，与报价仍有差距。据我的钢铁分析员了解，陕西地区Ca28Si55出厂含税价格在10200-11000元/吨，Ca30Si55价格在10500-11500元/吨；山西地区Ca28Si55价格在10500-11000元/吨，Ca30Si55价格在11000-11500元/吨，内蒙地区Ca28Si55价格在9600-13000元/吨，Ca30Si55价格在10000-13200元/吨，宁夏地区Ca28Si55含税到港价格在11200元/吨左右，Ca30Si55含税到港价格在11500元/吨左右。出口价格在出厂含税价上再加600-800元/吨左右。据我的钢铁网向国内各地生产企业了解，今日各地硅钙报价稍有下调，此次硅钙价格的变动主要是受国外采购厂家增多影响，前期价格稍稳，今日国外厂家采购基本告一段落，价格稍有回落。不少生产企业预计，后期即使硅钙出口关税增加20％，但是相对其它国家而言，中国硅钙的出口价格依然存在优势，所以邻国需要采购还是首先会考虑中国。关税通知的事实对硅钙国外采购实际的影响应该不会很大，主要还是受全球金融危机、钢材市场不景气的的影响较大。据了解，节内硅钙成交比较清淡，出口方面需求也有减少。虽然节日期间运输不便造成部分影响，但主要原因还是国内外市场不景气。目前需求企业为了将成本降到最低，都按每月需求量采购硅钙。由于需求的减少，只有部分企业依靠老客户在维持生计，大部分企业都遇到了出货难的问题，资金难以周转。许多厂家选择了停产检修、待销等手段来减少损失。其中内蒙地区的停产，减产厂家居多，其次是山西地区和陕西地区。有生产厂家表示：虽然现在市场上有消息宣称，8月中旬国内钢厂可能有一波硅钙采购，可以缓解眼下的压力。但是目前全球经济都处在一个非常时期，不能用以往的常理来推断。而且现在国内硅钙板价格生产企业拥有大量库存，即使中旬开始采购，不少厂家会选择积极出货，给采购商更多的选择空间，形势也不会太乐观。 

镍合金板价格在近几年里，随着我国对镍及镍合金扶持力度加大以及国家对镍及镍合金相关措施推出，鉴于镍及镍合金价格变化对于国内消费有着巨大的影响，加强对镍及镍合金市场的价格管理和调节显得十分重要。   镍基高温合金中应用最为广泛。主要原因在于，一是镍基合金中可以溶解较多合金元素，且能保持较好的组织稳定性；二是可以形成共格有序的 A3B型金属间化合物γ[Ni3(Al，Ti)]相作为强化相，使合金得到有效的强化，获得比铁基高温合金和钴基高温合金更高的高温强度；三是含铬的镍基合金具有比铁基高温合金更好的抗氧化和抗燃气腐蚀能力。镍基合金含有十多种元素，其中Cr主要起抗氧化和抗腐蚀作用，其他元素主要起强化作用。根据它们的强化作用方式可分为：固溶强化元素，如钨、钼、钴、铬和钒等；沉淀强化元素，如铝、钛、铌和钽；晶界强化元素，如硼、锆、镁和稀土元素等。        本报告从政策走势、市场运行、价格机制、影响因素、进出口贸易、经销企业、地区种植、储备运输等多个方面来研究镍及镍合金市场的价格走势及其成因。对于镍及镍合金企业、镍及镍合金价格管理部门都有很好的参考价值。   镍合金板价格与其他合金材料的即时更新尽在上海有色网 镍 专区。
