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.""

白铜熔点及优缺点在标准状况下~铜的熔点是1083.4度,铁的熔点是1534.8度……铜分黄铜，青铜，白铜 等……青铜的熔点比较低，约为800℃黄铜H62，H68熔点934度 黄铜H80熔点为967 度白铜熔点约为935℃白铜的优势与缺点纯铜加镍能显著提高强度、耐蚀性、硬度、电阻和热电性，并降低电阻率温度系数。因此白铜较其他铜合金的机械性能、物理性能都异常良好，延展性好、硬度高、色泽美观、耐腐蚀  白铜山水墨盒、富有深冲性能，被广泛使用于造船、石油化工、电器、仪表、医疗器械、日用品、工艺品等领域，并还是重要的电阻及热电偶合金。白铜的缺点是主要添加元素——镍属于稀缺的战略物资， 价格 比较昂贵。 　　镍白铜(有叫洋白铜)，用途：晶体振荡元件外壳，晶体壳体，电位器用滑动片，医疗机械，建筑材料等。以上就是白铜熔点及优缺点的介绍，更多信息请详见上海 有色金属 网

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。

紫铜熔点即是指紫铜由固态转变为液态的温度点。一般普通情况之下，紫铜的熔点为1083度，不同于黄铜和不锈钢的熔点，紫铜作为单质铜的主要品种之一，具有优良的导电性﹑导热性﹑延展性和耐蚀性。主要用于制作发电机﹑母线﹑电缆﹑开关装置﹑变压器等电工器材和热交换器﹑管道﹑太阳能加热装置的平板集热器等导热器材。常用的铜合金分为黄铜﹑青铜﹑白铜3大类。紫铜熔点高只是其一个优良物理特性之一，紫铜，就是铜单质，因其颜色为紫红色而得名。各种性质见铜。紫铜就是工业纯铜，其熔点为1083℃，无同素异构转变，相对密度为8.9，为镁的五倍。比普通钢还重约15%。其具有玫瑰红色，表面形成氧化膜后呈紫色，故一般称为紫铜。它是含有一定氧的铜，因而又称含氧铜。除了紫铜熔点之外，紫铜的其他性质也决定着紫铜的工业价值。紫铜因呈紫红色而得名。它不一定是纯铜，有时还加入少量脱氧元素或其他元素,以改善材质和性能，因此也归入铜合金。中国紫铜加工材按成分可分为：普通紫铜(T1、T2、T3、T4)、无氧铜（TU1、TU2和高纯、真空无氧铜）、脱氧铜（TUP、TUMn）、添加少量合金元素的特种铜（砷铜、碲铜、银铜）四类。紫铜的电导率和热导率仅次于银，广泛用于制作导电、导热器材。紫铜在大气、海水和某些非氧化性酸（盐酸、稀硫酸）、碱、盐溶液及多种有机酸（醋酸、柠檬酸）中，有良好的耐蚀性，用于化学工业。另外，紫铜有良好的焊接性，可经冷、热塑性加工制成各种半成品和成品。20世纪70年代，紫铜的 产量 超过了其他各类铜合金的总 产量 。紫铜中的微量杂质对铜的导电、导热性能有严重影响。其中钛、磷、铁、硅等显著降低电导率,而镉、锌等则影响很小。氧、硫、硒、碲等在铜中的固溶度很小,可与铜生成脆性化合物,对导电性影响不大，但能降低加工塑性。普通紫铜在含氢或一氧化碳的还原性气氛中加热时，氢或一氧化碳易与晶界的氧化亚铜(Cu2O)作用，产生高压水蒸气或二氧化碳气体，可使铜破裂。这种现象常称为铜的“氢病”。氧对铜的焊接性有害。铋或铅与铜生成低熔点共晶，使铜产生热脆；而脆性的铋呈薄膜状分布在晶界时，又使铜产生冷脆。磷能显著降低铜的导电性,但可提高铜液的流动性,改善焊接性。适量的铅、碲、硫等能改善可切削性。紫铜退火板材的室温抗拉强度为22～25公斤力／毫米2,伸长率为45～50％，布氏硬度（HB）为35～45。纯净的铜是紫红色的 金属 ，俗称“紫铜”、“红铜”或“赤铜”。 紫铜富有延展性。象一滴水那么大小的纯铜，可拉成长达两公里的细丝，或压延成比床还大的几乎透明的箔。紫铜最可贵的性质是导电性能非常好，在所有的 金属 中仅次于银。但铜比银便宜得多，因此成了电气工业的“主角”。2.鉴于紫铜熔点相对较高等各方面特点，其工业用途也被广泛开发：紫铜的用途比纯铁广泛得多，每年有50%的铜被电解提纯为纯铜，用于电气工业。这里所说的紫铜，确实要非常纯，含铜达99.95%以上才行。极少量的杂质，特别是磷、砷、铝等，会大大降低铜的导电率。铜中含氧(炼铜时容易混入少量氧)对导电率影响很大，用于电气工业的铜一般都必须是无氧铜。另外，铅、锑、铋等杂质会使铜的结晶不能结合在一起，造成热脆，也会影响纯铜的加工。这种纯度很高的纯铜，一般用电解法精制：把不纯铜(即粗铜)作阳极，纯铜作阴极，以硫酸铜溶液为电解液。当电流通过后，阳极上不纯的铜逐渐熔解，纯铜便逐渐沉淀在阴极上。这样精制而得的铜;纯度可达99.99%。紫铜熔点较高，使紫铜能够耐高温，成为了工业用主要 金属 之一，除了上述介绍的紫铜的用途之外，紫铜的 价格 也就成为了紫铜生产厂家及厂商所关注的焦点，紫铜 价格 报价也就至关重要。上海 有色 网提供专业的 有色金属 相关报价及其他资讯相关服务，更多相关信息，请查询上海 有色金属 网！

氧化铜的熔点为1326℃物质的熔点（melting point)，即在一定压力下，纯物质的固态和液态呈平衡时的温度，也就是说在该压力和熔点温度下，纯物质呈固态的化学势和呈液态的化学势相等，而对于分散度极大的纯物质固态体系（纳米体系）来说，表面部分不能忽视，其化学势则不仅是温度和压力的函数，而且还与固体颗粒的粒径有关。铜的熔点为1084 ℃，可见氧化铜熔点高于铜的熔点，在高温条件下，氧化铜的稳定性高于金属铜。

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。

黄铜是铜锌合金，根据合金定律，黄铜的熔点肯定低于纯铜，随着锌含量的不同而变换，黄铜H62，H68熔点934度 黄铜H80熔点为967。

锌是一种蓝白色金属。密度为7.14克/立方厘米，锌的熔点为419.5℃。在室温下，性较脆；100～150℃时，变软；超过200℃后，又变脆。锌作为一种常见的金属,大家对它的性质基本都了解了.但是熔点是什么呢?让小编来告诉您.熔点是固体将其物态由固态转变（熔化）为液态的温度。进行相反动作（即由液态转为固态）的温度，称之为凝固点。与沸点不同的是，熔点受压力的影响很小。而大多数情况下一个物体的熔点就等于凝固点。晶体开始融化时的温度叫做熔点。物质有晶体和非晶体,晶体有熔点,而非晶体则没有熔点。晶体又因类型不同而熔点也不同.一般来说晶体熔点从高到低为,原子晶体>离子晶体>金属晶体>分子晶体。在分子晶体中又有比较特殊的,如水,氨气等.它们的分子只间因为含有氢键而不符合"同主组元素的氢化物熔点规律性变化''的规律。锌的熔点是锌的一个物理性质。锌的熔点并不是固定不变的，有两个因素对熔点影响很大。一是压强，平时所说的物质的熔点，通常是指一个大气压时的情况；如果压强变化，熔点也要发生变化。熔点随压强的变化有两种不同的情况．对于大多数物质，熔化过程是体积变大的过程，当压强增大时，这些物质的熔点要升高；对于像水这样的物质，与大多数物质不同，冰熔化成水的过程体积要缩小(金属铋、锑等也是如此)，当压强增大时冰的熔点要降低。另一个就是物质中的杂质，我们平时所说的物质的熔点，通常是指纯净的物质。但在现实生活中，大部分的物质都是含有其它的物质的，比如在纯净的液态物质中熔有少量其他物质，或称为杂质，即使数量很少，物质的熔点也会有很大的变化，例如水中熔有盐，熔点就会明显下降，海水就是熔有盐的水，海水冬天结冰的温度比河水低，就是这个原因。饱和食盐水的熔点可下降到约-22℃，北方的城市在冬天下大雪时，常常往公路的积雪上撒盐，只要这时的温度高于-22℃，足够的盐总可以使冰雪熔化，这也是一个利用熔点在日常生活中的应用。更多有关锌的熔点和锌的咨询,欢迎登陆上海有色网!    

铜的熔点是铜的物理性质的一种，为1083.4±0.2℃。让我们一起来补充一下铜的基础知识吧。铜是人类最早发现的古老金属之一，早在三千多年前人类就开始使用铜。自然界中的铜分为自然铜、氧化铜矿和硫化铜矿。自然铜及氧化铜的储量少，现在世界上80%以上的铜是从硫化铜矿精炼出来的，这种矿石含铜量极低，一般在2-3%左右。金属铜，元素符号CU，原子量63.54,比重8.92，铜的熔点1083.4±0.2℃。纯铜呈浅玫瑰色或淡红色。铜具有许多可贵的物理化学特性，例如其热导率都很高，化学稳定性强，抗张强度大，易熔接，且抗蚀性、可塑性、延展性。纯铜可拉成很细的铜丝，制成很薄的铜箔。能与锌、锡、铅、锰、钴、镍、铝、铁等金属形成合金，形成的合金主要分成三类：黄铜是铜锌合金，青铜是铜锡合金，白铜是铜钴镍合金。铜的冶炼      从铜矿中开采出来的铜矿石，经过选矿成为含铜品位较高的铜精矿或者说是铜矿砂，铜精矿需要经过冶炼提成,才能成为精铜及铜制品。A．铜矿石的加工      工业上使用的铜有电解铜（含铜99.9％～99.95％）和精铜（含铜99.0％～99.7％）两种。前者用于电器工业上，用于制造特种合金、金属丝及电线。后者用于制造其他合金、铜管、铜板、轴等。a.铜矿石的分类及属性：炼铜的原料是铜矿石。铜矿石可分为三类：（1）硫化矿，如黄铜矿(CuFeS2)、斑铜矿(Cu5FeS4)和辉铜矿(Cu2S)等。（2）氧化矿，如赤铜矿(Cu2O)、孔雀石[CuCO3·Cu(OH)2]、蓝铜矿[2CuCO3·Cu(OH)2]、硅孔雀石(CuSiO3·2H2O)等。（3）自然铜。铜矿石中铜的含量在1％左右（0.5％～3％）的便有开采价值，因为采用浮选法可以把矿石中一部分脉石等杂质除去，而得到含铜量较高（8％～35％）的精矿砂。b.铜矿石的冶炼过程：      从铜矿石冶炼铜的过程比较复杂。以黄铜矿为例，首先把精矿砂、熔剂（石灰石、砂等）和燃料（焦炭、木炭或无烟煤）混合，投入“密闭”鼓风炉中，在1000℃左右进行熔炼。于是矿石中一部分硫成为SO2（用于制硫酸），大部分的砷、锑等杂质成为AS2O3、Sb2O3等挥发性物质而被除去：2CuFeS2＋O2=Cu2S＋2FeS＋SO2↑。一部分铁的硫化物转变为氧化物：2FeS＋3O2=2FeO＋2SO2↑。Cu2S跟剩余的FeS等便熔融在一起而形成“冰铜”（主要由Cu2S和FeS互相溶解形成的，它的含铜率在20％～50％之间，含硫率在23％～27％之间），FeO跟SIO2形成熔渣：FeO＋SiO2=FeSiO3。熔渣浮在熔融冰铜的上面，容易分离，借以除去一部分杂质。然后把冰铜移入转炉中，加入熔剂（石英砂）后鼓入空气进行吹炼（1100°～1300℃）。由于铁比铜对氧有较大的亲和力，而铜比铁对硫有较大的亲和力，因此冰铜中的FeS先转变为FeO，跟熔剂结合成渣，而后Cu2S才转变为Cu2O，Cu2O跟Cu2S反应生成粗铜（含铜量约为98.5％）。2Cu2S＋3O2=2Cu2O＋2SO2↑，2Cu2O+Cu2S=6Cu+SO2↑，再把粗铜移入反射炉，加入熔剂（石英砂），通入空气，使粗铜中的杂质氧化，跟熔剂形成炉渣而除去。在杂质除到一定程度后，再喷入重油，由重油燃烧产生的一氧化碳等还原性气体使氧化亚铜在高温下还原为铜。得到的精铜约含铜99.7％。B.铜的冶炼工艺      铜治金技术的发展经历了漫长的过程，但至今铜的冶炼仍以火法治炼为主，其产量约占世界铜总产量的85%，现代湿法冶炼的技术正在逐步推广，湿法冶炼的推出使铜的冶炼成本大大降低。 火法冶炼与湿法冶炼（SX－EX）。a.火法炼铜:       通过熔融冶炼和电解精火炼生产出阴极铜，也即电解铜，一般适于高品位的硫化铜矿。火法冶炼一般是先将含铜百分之几或千分之几的原矿石，通过选矿提高到20－30％，作为铜精矿，在密闭鼓风炉、反射炉、电炉或闪速炉进行造锍熔炼，产出的熔锍(冰铜)接着送入转炉进行吹炼成粗铜，再在另一种反射炉内经过氧化精炼脱杂，或铸成阳极板进行电解，获得品位高达99.9％的电解铜。该流程简短、适应性强，铜的回收率可达95％，但因矿石中的硫在造锍和吹炼两阶段作为二氧化硫废气排出，不易回收，易造成污染。近年来出现如白银法、诺兰达法等熔池熔炼以及日本的三菱法等、火法冶炼逐渐向连续化、自动化发展。 生产过程大致如图：      除了铜精矿之外,废铜做为精炼铜的主要原料之一，包括旧废铜和新废铜，旧废铜来自旧设备和旧机器，废弃的楼房和地下管道；新废铜来自加工厂弃掉的铜屑(铜材的产出比为50％左右),一般废铜供应较稳定，废铜可以分为：裸杂铜:品位在90％以上；黄杂铜（电线）:含铜物料（旧马达、电路板）；由废铜和其他类似材料生产出的铜，也称为再生铜。 b.湿法炼铜:       一船适于低品位的氧化铜，生产出的精铜称为电积铜。 现代湿法冶炼有硫酸化焙烧－浸出－电积，浸出－萃取－电积，细菌浸出等法，适于低品位复杂矿、氧化铜矿、含铜废矿石的堆浸、槽浸选用或就地浸出。湿法冶炼技术正在逐步推广，预计本世纪末可达总产量的20%，湿法冶炼的推出使铜的冶炼成本大大降低。湿法冶炼过程为： c.火法和湿法两种工艺的特点 比较火法和湿法两种铜的生产工艺，有如下特点： （1）后者的冶炼设备更简单，但杂质含量较高，是前者的有益补充。（2）后者有局限性，受制于矿石的品位及类型。 （3）前者的成本要比后者高。可见，湿法冶炼技术具有相当大的优越性，但其适用范围却有局限性，并不是所有铜矿的冶炼都可采用该种工艺。不过通过技术改良，这几年已经有越来越多的国家，包括美国、智利、加拿大、澳大利亚、墨西哥及秘鲁等，将该工艺应用于更多的铜矿冶炼上。湿法冶炼技术的提高及应用的推广，降低了铜的生产成本，提高了铜矿产能，短期内增加了社会资源供给，造成社会总供给的相对过剩，对价格有拉动作用。想知道更多关于铜的熔点的知识，您可以登陆上海有色网进行查看 。 

纯铜熔点为1083.4±0.2℃。无缝药芯焊丝是铝铜钎焊连接的最新技术成果，是铝铜钎焊用料的升级换代产品。其主要成分由锌铝铜和无腐蚀性氟铝铯盐组成，其钎焊工艺性、接头机械性能和接头导电性均优于锌镉、锌锡铜钎料。广泛用于电力电器、信息电子、不锈钢制品、制冷 行业 、电热电器、五金制品等 行业 。不需专用焊接设备和特殊生产场地，即可实现环保、便捷、安全的铝铜连接。其中铜包含常见的铜合金，铝主要指1系列、3系列和6系列和部分4系列。郑州机械研究所是目前国内主要的无缝药芯铝焊丝生产企业，已有50余年的钎焊材料及钎焊工艺研究的历史，是中国焊接学会及国家焊接标准化委员会团体会员。该铜铝焊接钎料已在制冷,变压器,电机等铜改铝 行业 得到成熟的应用。铜及铜合金的焊接特点是：(1)难熔合及易变形；(2)容易产生热裂纹；(3)容易产生气孔。铜及铜合金焊接主要采用气焊、惰性气体保护焊、埋弧焊、钎焊等方法。铜及铜合金导热性能好，所以焊接前一般应预热，并采用大线能量焊接。钨极氢弧焊采用直流正接。气焊时，紫铜采用中性焰或弱碳化焰，黄铜则采用弱氧化焰，以防止锌的蒸发。铜矿石的冶炼过程：从铜矿石冶炼铜的过程比较复杂。以黄铜矿为例，首先把精矿砂、熔剂（石灰石、砂等）和燃料（焦炭、木炭或无烟煤）混合，投入“密闭”鼓风炉中，在1000℃左右进行熔炼。于是矿石中一部分硫成为SO2（用于制硫酸），大部分的砷、锑等杂质成为AS2O3、Sb2O3等挥发性物质而被除去：2CuFeS2＋O2=Cu2S＋2FeS＋SO2↑。一部分铁的硫化物转变为氧化物：2FeS＋3O2=2FeO＋2SO2↑。Cu2S跟剩余的FeS等便熔融在一起而形成“冰铜”（主要由Cu2S和FeS互相溶解形成的，它的含铜率在20％～50％之间，含硫率在23％～27％之间），FeO跟SiO2形成熔渣：FeO＋SiO2=FeSiO3。熔渣浮在熔融冰铜的上面，容易分离，借以除去一部分杂质。然后把冰铜移入转炉中，加入熔剂（石英砂）后鼓入空气进行吹炼（1100～1300℃）。由于铁比铜对氧有较大的亲和力，而铜比铁对硫有较大的亲和力，因此冰铜中的FeS先转变为FeO，跟熔剂结合成渣，而后Cu2S才转变为Cu2O，Cu2O跟Cu2S反应生成粗铜（含铜量约为98.5％）。2Cu2S＋3O2=2Cu2O＋2SO2↑，2Cu2O+Cu2S=6Cu+SO2↑，再把粗铜移入反射炉，加入熔剂（石英砂），通入空气，使粗铜中的杂质氧化，跟熔剂形成炉渣而除去。在杂质除到一定程度后，再喷入重油，由重油燃烧产生的一氧化碳等还原性气体使氧化亚铜在高温下还原为铜。得到的精铜约含铜99.7％。铜的冶炼工艺：铜冶金技术的发展经历了漫长的过程，但至今铜的冶炼仍以火法治炼为主，其 产量 约占世界铜总 产量 的85%，现代湿法冶炼的技术正在逐步推广，湿法冶炼的推出使铜的冶炼成本大大降低。 火法冶炼与湿法冶炼（SX－EX）。火法炼铜：通过熔融冶炼和电解精火炼生产出阴极铜，也即电解铜，一般适于高品位的硫化铜矿。火法冶炼一般是先将含铜百分之几或千分之几的原矿石，通过选矿提高到20－30％，作为铜精矿，在密闭鼓风炉、反射炉、电炉或闪速炉进行造锍熔炼，产出的熔锍(冰铜)接着送入转炉进行吹炼成粗铜，再在另一种反射炉内经过氧化精炼脱杂，或铸成阳极板进行电解，获得品位高达99.9％的电解铜。该流程简短、适应性强，铜的回收率可达95％，但因矿石中的硫在造锍和吹炼两阶段作为二氧化硫废气排出，不易回收，易造成污染。近年来出现如白银法、诺兰达法等熔池熔炼以及日本的三菱法等、火法冶炼逐渐向连续化、自动化发展。纯铜熔点决定纯铜作为焊接的好材料。 

钨的熔点为：3380℃  其沸点可达到 5927℃ 。接下来我们在来更深入的了解一下什么是钨。钨是一种金属元素。原子序数74。钢灰色或银白色,硬度高,熔点高,常温下不受空气侵蚀;主要用途是制造灯丝和高速切削合金钢、超硬模具,也用于光学仪器,化学仪器方面 tungsten;wolfram——元素符号W。钨是属于有色金属，也是重要的战略金属，钨矿在古代被称为“重石”。1781年由瑞典化学家卡尔．威廉．舍耶尔发现白钨矿，并提取出新的元素酸－钨酸，1783年被西班牙人德普尔亚发现黑钨矿也从中提取出钨酸，同年，用碳还原三氧化钨第一次得到了钨粉，并命名该元素。钨在地壳中的含量为0.001%。已发现的含钨矿物有20种。钨矿床一般伴随着花岗质岩浆的活动而形成。经过冶炼后的钨是银白色有光泽的金属，熔点极高，硬度很大。钨是稀有高熔点金属，属于元素周期表中第六周期（第二长周期）的VIB族。钨是一种银白色金属，外形似钢。钨的熔点高，蒸气压很低，蒸发速度也较小。钨的化学性质很稳定，常温时不跟空气和水反应，不加热时，任何浓度的盐酸、硫酸、硝酸、氢氟酸以及王水对钨都不起作用，当温度升至80°—100°C 时，上述各种酸中，除氢氟酸外，其它的酸对钨发生微弱作用。常温下，钨可以迅速溶解于氢氟酸和浓硝酸的混合酸中，但在碱溶液中不起作用。有空气存在的条件下，熔融碱可以把钨氧化成钨酸盐，在有氧化剂（NaNO3、NaNO2、KClO3、PbO2）存在的情况下，生成钨酸盐的反应更猛烈。高温下能与氯、溴、碘、碳、氮、硫等化合，但不与氢化合。目前世界上开采出的钨矿，约５０%用于优质钢的冶炼，约３５%用于生产硬质钢，约１０%用于制钨丝，约５％其他用于其他用途。钨可以制造枪械、火箭推进器的喷嘴、切削金属的刀片、钻头、超硬模具、拉丝模等等，钨的用途十分广泛，涉及矿山、冶金、机械、建筑、交通、电子、化工、轻工、纺织、军工、航天、科技、各个工业领域。钨是稀有金属，也是重要的战略物资。我国是产钨大国，钨资源储量520万吨，占世界总储量的65％，产量及出口量均居世界第一。湖南、江西、河南三省的钨资源储量居全国的前三位，其中湖南、江西两省的钨资源储量占全国的55．48％。湖南以白钨为主，江西以黑钨为主，其黑钨资源占全国黑钨资源总量的42．40％。钨的熔点或是其他更多有关金属方面疑问，请登入上海有色网查询。

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
