随着 市场 对紫铜需求的日益增大，对于其购买都是采用批发紫铜的买法。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。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。 　　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”。批发出售有利于更好的将紫铜推向 市场 ，想要了解更多关于紫铜批发的信息，请继续浏览上海 有色 网。

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。

2009年中国裸铜线批发 市场 发展迅速，产品产出持续扩张，在国家 产业 政策的鼓励下， 行业 产品向高技术产品方向发展，国内企业新增投资项目逐渐增多。投资者对 行业 关注越来越密切，这使得裸铜线 行业 的发展需求不断增大。  2009年10月-2010年3月铜电线 价格 ：BV 2.5平方电线 价格 :145元/盘 BV 4平方电线 价格 :236元/盘 BV 6平方电线 价格 ：363元/盘  2009年8月国内 现货 铜线批发 价格 达到37000元 /吨的高位，但 期货价格 却不为所动，在连续6个 交易 日里自最高价下跌了1000元/吨。相比于上海铜价，LME和COMEX的 走势 显得更加疲弱，LME3 月铜 价格 反弹到3320美元后就调头向下，根本没有触及倒3338美元的记录新高，经过5个 交易 日的下跌已经回到3200美元以下。在 价格 温和下跌一定幅度后， 市场 上消费买盘纷纷进入也吸引了一部分以牛市思维进场的抄底买盘。对于 价格 后市如何演绎，铜价运行趋势是否转变，笔者综合几方面的因素进行了分析，得出这样的结论：铜价牛熊转换正在进行，如果 价格 跌破关键的支撑将加速下跌，并开始熊市。

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.""

    批发就是指专门从事大宗商品 交易 的商业活动。零售的对称。是商品流通中不可缺少的一个环节。通常有两种情况：①商业企业将商品批量售给其他商业企业用作转卖。②商业企业将用作再加工的生产资料供应给生产企业。而铜合金批发指主要从事大量铜合金产品 交易 的商业活动.   铜合金（copper alloy ）以纯铜为基体加入一种或几种其他元素所构成的合金。纯铜呈紫红色﹐又称紫铜。纯铜密度为8.96﹐熔点为1083℃﹐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。  批发是随着商品经济的发展而产生的。商品生产和商品交换的发展，使商品购销量增大，流通范围扩展，生产者相互之间、生产者与零售商之间直接进行商品交换，常有困难或不方便，于是产生了专门向生产者直接购进商品，然后再转卖给其他生产者或零售商的批发商业，商业部门内部有了批发和零售之间的分工。批发业务一般由批发企业来经营，每次批售的商品数量较大，并按批发 价格 出售。商品的批发 价格 低于零售 价格 ，即存在着批零差价，其差额由零售企业所耗费的流通费用、税金和利润构成。商业批发是生产与零售之间的中间环节。通过商业批发活动，使社会产品从生产领域进入流通领域，起到组织和调动地区之间商品流通的作用。还可通过商品储存发挥“蓄水池”作用，平衡商品供求。   铜合金批发以铜及铜合金材料为主做的大批量商品流通,购销及交换.随着铜材 市场 的需求供大,越来越多的商家或企业会选择批发来经营或购买铜材.

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。

废镍料一定要具有有铁磁性和延展性，能导电和导热。常温下，镍在潮湿空气中表面形成致密的氧化膜，不但能阻止继续被氧化，而且能耐碱、盐溶液的腐蚀。块状镍不会燃烧，细镍丝可燃，特制的细小多孔镍粒在空气中会自燃。加热时，镍与氧、硫、氯、溴发生剧烈反应。细粉末状的金属镍在加热时可吸收相当量的氢气。镍能缓慢地溶于稀盐酸、稀硫酸、稀硝酸，但在发烟硝酸中表面钝化。镍的氧化态为－1、＋1、＋2、＋3、＋4 ，简单化合物中以＋2价最稳定，＋3价镍盐为氧化剂。镍的氧化物有NiO和Ni2O3。氢氧化镍〔Ni(OH)2〕为强碱，微溶于水，易溶于酸。硫酸镍（NiSO4）能与碱金属硫酸盐形成矾 Ni(SO4)2o6H2O(MI为碱金属离子)。＋2价镍离子能形成配位化合物。在加压下，镍与一氧化碳能形成四羰基镍〔Ni（CO）4〕，加热后它又会分解成金属镍和一氧化碳。 　　废镍料银白色金属，密度8.9克/厘米3。熔点1455℃，沸点2730℃。化合价2和3。电离能为7.635电子伏特。质坚硬，具有磁性和良好的可塑性。有好的耐腐蚀性，在空气中不被氧化，又耐强碱。在稀酸中可缓慢溶解，释放出氢气而产生绿色的正二价镍离子Ni2+；对氧化剂溶液包括硝酸在内，均不发生反应。镍是一个中等强度的还原剂。废镍料大量用于再次制造合金。在钢中加入镍，可以提高机械强度。如钢中含镍量从2．94％增加到了7.04％时，抗拉强度便由52．2公斤／毫米2增加到72．8公斤／毫米3。镍钢用来制造机器承受较大压力、承受冲击和往复负荷部分的零件，如涡轮叶片、曲轴、连杆等。含镍36％、含碳0.3-0．5％的镍钢，它的膨胀系数非常小，几乎不热胀冷缩，用来制造多种精密机械，精确量规等。含镍46％、含碳0．15％的高镍钢，叫“类铂”，因为它的膨胀系数与铂、玻璃相似，这种高镍钢可熔焊到玻璃中。在灯泡生产上很重要，可作铂丝的代用品。一些精密的透镜框，也用这种类铂钢做，透镜不会因热胀冷缩而从框中掉下来。由67．5％镍、16％铁、15％铬、1．5％锰组成的合金，具有很大的电阻，用来制造各种变阻器与电热器。

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。

磷铜钎料  铜磷钎料适宜于钎焊铜及黄铜，但是不适宜钎焊黑色 金属 。这类儿钎料能很好的湿润铜及黄铜，并扩散到边缘层，接头的脆性比钎料本身小。但铜磷钎料对黑色 金属 的湿润性很差，在结合处形成脆性磷化物，使接头脆性增大。钎料中的磷可以还原氧化铜和氧化银，起着钎焊熔剂作用。因此铜磷钎料钎焊铜和银时，可以不需要钎焊熔剂，但在钎焊铜合金时，因为磷不能充分地还原铜的合金元素形成的氧化物，为了获得优质钎缝，还应与钎焊熔剂配合使用，钎焊接头的最好间隙为0.03～0.075mm.  铜-磷合中加入银会大大地提高焊料湿润能力，提高强度和韧性，降低熔点。　钎焊时若加热过程缓慢，铜磷钎料有偏析倾向，帮钎焊时加热速度尽可憎快些，焊后的颜色是亮灰色，浸在10％硫酸中将恢复铜的颜色。1.ScuP-2是接近共晶粉的铜磷钎料，熔点较低，具有良好的湿润性，可以流入间隙很小钎缝。钎料的 价格 便宜，所以获得谅的应用。但钎缝塑性差，处在冲击和弯曲状态的接头不宜采用。电阻率为0.28Ω。mm2／m.　　用途：广泛用于电机制造和仪表工业上钎焊铜及铜合金。　　1.ScuP-3是含砂磷稍低的铜磷钎料，与HL201比较，熔化温度稍高，温流性稍差而塑性略有改善，但仍脆，故处于冲击和弯曲工作状态的接头不宜采用，电阴率为0.25Ω。mm2／m.　　用途：适用电机制造和仪表工业上钎焊铜及铜合金。　　2.SAgP-2钎料含银量低，熔点适中塑性较好，具有良好的漫流性和填缝能力，接头机械性能好，对于铜和铜的钎焊具有自钎性。电阻率约为0.32Ω。mm2／m.　　用途：适用于电机制造和仪表工业上钎焊铜及铜合金。　　3.SAP-5是含银5％的铜银磷钎料，其钎焊接头强度、塑性、导电性及漫流性比SAgP-5稍差，但比ScuP-2有所改善。电阻率约为0.23Ω。mm2／m.　　用途：适用于电机制造和仪表工业上钎焊铜及铜合金。　　4.SAgP-15是含15％银的铜银磷钎料，由于银的加入，提高了强度减少脆性，钎钎料熔点降低，其接头强度、塑性、导电性及漫流性是铜磷钎料中最好的一种，对接头的准备及装配相对说来要求较低。电阻率约0.12Ω。mm2／m.　　用途：适用于钎焊铜及铜合金、银、钼等 金属 。多数用来钎焊冲击振动负载较小的工作，以电机制造使用最广。　　ScuP-6Sn是含锡的铜磷钎料，能使钎焊温度降低，钎焊接头强度较好，减少了脆性，是导电性及流动性较好的铜磷锡钎料中是理想的一种钎料。　　用途：适用于钎焊铜及铜合金等 金属 材料，在电机、空调器，冷冻机制造工业上广泛应用。　　注意事项：　　1.钎焊前必须严格清除钎焊处及钎料表面的油脂、氧化物等污物。　　2.钎焊铜时不用钎焊熔剂，但钎焊铜合金时应配合钎剂使用。

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

冷轧板卷是以热轧卷为原料，在室温下在再结晶温度以下进行轧制而成，包括板和卷，国内众多钢厂如宝钢、武钢、鞍钢等均可以生产。其中成张交货的称为钢板，也称盒板或平板；长度很长、成卷交货的称为钢带，也称卷板。 生产过程中由于不进行加热，所以不存在热轧常出现的麻点和氧化铁皮等缺陷，表面质量好、光洁度高。而且冷轧产品的尺寸精度高，产品的性能和组织能满足一些特殊的使用要求，如电磁性能、深冲性能等。  　　规格：厚度为0.2-4mm，宽度为600-2 000mm，钢板长度为1 200-6 000mm。  　　牌号：Q195A-Q235A、Q195AF-Q235AF、Q295A(B)-Q345 A(B)；SPCC、SPCD、SPCE、ST12-15;DC01-06  　　性能：主要采用低碳钢牌号，要求具有良好的冷弯和焊接性能，以及一定的冲压性能。 钢号规格（厚*宽*长）冷轧板规格板0.4*1000*C0.5*1250*C0.35*1000*C 1.0*1000*C0.7*1020*C0.3*1000*C 0.4*1000*C1.5*1000*C2.5*1000*C 2.5*1000*C2.0*1250*C1.5*1250*C 1.0*1250*C1.0*1000*C1.0*1000*2000 1.2*1000*20001.5*1000*20000.5*1000*C 2.0*1000*20003.0*1000*20001.0*1250*2000 1.0*1250*25001.2*1250*20001.2*1250*2500 1.5*1250*20001.5*1250*20002.0*1250*2000 2.0*1250*25002.5*1250*20002.5*1250*2500 3.0*1250*20003.0*1250*25001.0*1250*2500 0.35*1000*20000.4*1000*20000.45*1000*2000 0.5*1000*20000.6*1000*20000.7*1000*2000 0.8*1000*20002.0*1000*20001.2*1000*2000 1.5*1000*20001.0*1250*2000

铝板基外表处置 A对铝板基的技能需求 对制造PS版的铝板基较基本的技能需求是外表光滑平坦，无擦划伤、坑包、印痕、非金履压入、气孔、轧制条纹等表观缺点，厚薄一致，波涛度操控在1mm内，平直度小于2I;组织细密均匀，无偏析、夹渣，内应力分由对称、均匀;粗糙度Ra值小于0.28，以确保电解砂目细密均匀。目前我国很多运用的板基材料为1050A、1060等。 B碱洗 一般，由铝加工厂供给的铝板，其外表都带有一定量的油，油和氧化膜对砂目处置有影响，在PS版出产中常用热碱冲刷铝板进行外表处置。 一般用碱液来去掉氧化膜和油。常用除油液的配比为：NaOH的质量钠等缓蚀剂及葡萄糖酸钠、脂肪酸聚氧乙烯醚类增溶、络合等外表活性剂。 除油液的温度一般操控在55～60℃左右，除油的作用与溶液的温度有关。若温度太高，则造民对铝板基严重腐蚀，因此有必要操控温度。 除油的时刻有必要通过仔细对比较终断定。由于，它与各种不一样出产线有关。卷筒出产线则与出产线的速度有关，以4m/min为例，除油时刻有必要这到20s，其作用才能处以确保。 除油液有必要留意及时更新，由于在除油进程中会生成很多的皂化物、乳化物和铝盐，它们的存在影响除油作用，并阻止对铝板外表油污的皂化和乳化，当发现除油作用不强时，有必要及时更新。一般若通过碱泵进行循环时，除油液能坚持较长时刻，若不循环则更新时刻缩短。 查看除油作用较简单的方法是用水。除油作用好的铝板外表水能均匀地附着涣散，若水倒上后，在铝板外表呈水珠状，则阐明除油作用欠好。除油的温度要常常留意，除油液的温度过低，则能够构成除油不完全。 C酸洗 在出产工艺中，碱洗以后有一硝酸酸洗进程，其目的是去掉碱洗后的残留物质，中和剩余的碱液。硝酸溶液的质量浓度为5%～10%。配制时留意将硝酸小心肠倒入水中，充分混合。在酸洗进程中应常常留意溶液的浓度剖析，及时弥补。 D粗化 粗化是为了构成具有需求粗糙度的砂目构造。粗化既可进步铝板基外表对水的亲和力，进步板基外表湿润量，避免版面上脏;一起粗化后的外表还可进步版同与感光剂的附着力，进而进步印版的耐印力。 粗化后的砂目是由无数的凸峰和凹谷构成，不一样的砂目构造，对保水性感光层的附着力影响较大，并对PS版的运用带来较大影响。出产顶用外表粗糙度测试仪制作的砂目粗糙断面轮廓曲线的特征参数来表征。

镍基合金焊条的分类与用途：镍及镍合金焊条可分为五大类，即工业纯Ni、Ni-Cu、Ni-Cr-Fe、Ni-Mo和Ni-Cr-Mo。每一类可分为一种或多种型号的焊条。这类焊条主要用于焊接镍或高镍合金，有时也可用于异种 金属 的焊接或堆焊。镍基合金焊条的选用，用于焊接低碳镍铬钼合金，纯镍焊条 A5.11 ENi-1 EL-NiTi3 ≥ 92 - - Ti2.5 - 焊接 200 、 201 镍合金以及镀镍钢板； - 钢与镍异种材料的焊接； - 钢的表面堆焊。镍基合金焊条成份对比Ni307镍及镍合金焊条 型号GB/T：ENiCrMo-0说明：低氢型Ni70Cr15耐热耐蚀合金焊条，焊缝中有适量的钼、铌等合金元素，熔敷 金属 具有良好的抗裂性，采用直流反接。用途：用于焊接有耐热、耐蚀要求的镍基合金，也可用于一些难焊合金、异种钢的焊接及堆焊。熔敷 金属 化学成份/% C≈0.05 Ni≈70 Fe≤7 Nb 3-5 Mo 2-6 Cr≈15   Ni307A镍及镍合金焊条 型号GB/T：ENiCrFe-3 相当于AWS：ENiCrFe-3说明：低氢型Ni70Cr15耐热合金焊条，焊缝中有适量的锰、铌等合金元素，熔敷 金属 具有良好的抗裂性，采用直流反接。用途：用于焊接有耐热、耐蚀要求的镍基合金，如因康镍600、601等，也可用于一些难焊合金、异种钢的焊接及堆焊。熔敷 金属 化学成份/% ；C≤0.1 Mn 5-9.5 Si≤1 Ni 59 Fe≤10 Ti≤1 Nb+Ta 1-2.5 ；S≤0.015 P≤0.03 Cu≤0.5 Cr 13-17Ni307B镍及镍合金焊条 型号GB/T：ENiCrFe-3 相当于AWS：ENiCrFe-3镍基合金焊条 A5.11 ENiCu-7 EL-NiCu30Mn 65 - - Mn ≤ 4.0 其余为铜 - 蒙乃尔 400 合金自身的焊接；以及蒙乃尔 400 合金与钢的焊接； - 用于钢的表面堆焊。铜镍焊条 A5.6 ECuNi S-CuNi30Mn ≥ 29 - - Mn2 其余为铜 - 用于铜镍合金以及特定的青铜材料自身的焊接，以及这些材料和蒙乃尔 400 合金或 Nickel200 之间的焊接。镍基合金焊条 A5.11 ENiCrFe-2 EL-NiCr15FeNb ≥ 62 15 1.5 Mn2.5 Nb1.5 - 抗蠕变接头的焊接、异种材料焊接；奥氏体、铁素体钢和高镍合金的焊接、含镍 9% 。镍基合金焊条也在各个领域内具有相当广泛的应用，未来发展前景巨大。

镍基合金焊条在市场上算是一种比较热销的产品，所以让我们来详细的了解下镍基合金焊条。我想这样对您会有所帮助的。（1）镍及镍基合金焊条的选用原则 镍及镍基合金焊条主要根据被焊母材的合金牌号、化学成分和使用环境等条件选用。焊条的熔敷金属的主要化学成分应与母材的主要成分想接近，以保证焊接接头的各项性能与母材相当。但考虑到焊条在电弧中的合金损失，在焊条中还应含有一些其他元素，以改善焊缝性能或焊接工艺性能。 　　若采用相同成分的焊条达不到设计要求或者没有合适的类似合金成分的焊条时，则推荐选用性能高一级别的焊条，以保证焊缝的使用性能不低于母材。 　　（2）镍及镍基合金焊条的使用注意事项 　　① 母材的准备：焊前应认真清除母材表面的油污、油漆、灰尘等脏物。 　　② 为防止气孔，采用短弧焊接。 　③ 采用较小焊接电流，焊前不预热，保持较低道间温度（＜150℃），以避免母材过热。 　　④ 焊接时焊条摆动幅度要小，焊道两侧停留稍长时间，以利气孔和焊渣的浮出。 　　⑤ 收弧时注意填充满弧坑，以免产生弧坑裂纹。 　　⑥ 镍及镍基合金焊条的显微组织为奥氏体，有强的热裂纹倾向，在焊接角焊缝时，要求焊道呈凸起状，这样可以较好地防止热裂纹的产生。更多有关镍基合金焊条 价格或是其他金属价格，请登入上海有色网 www.smm.cn
