紫铜板和黄铜板的差异其实咱们从称号上就能够看出来一点：色彩不同。除了色彩外，紫铜板和黄铜板在组成成分、功用和用处上都有不同。下面咱们就来看一下紫铜板和黄铜板有哪些差异。1.组成成分不同：紫铜很纯洁，几乎是纯铜，具有杰出的导电性和可塑性，强度和硬度稍弱小一些；黄铜中还含有其它合金，报价低廉，导电性和可塑性与紫铜比较稍弱小一点，但是有较高的强度和硬度。2.功用不同：紫铜的含铜量为99.9%，导电性、导热性、耐性、焊接性以及抗腐蚀性优秀；黄铜的密度比紫铜大，有杂质，具有优秀的耐腐蚀性，导电率比紫铜低。3.用处不同：紫铜板常用于导电、导热器件的制造，因其有较好的耐腐蚀性，还常被用于化工行业，通过冷塑性和热塑性的加工，能够制成半制品或许制品；黄铜耐腐蚀，常用于弹性元件、五金以及装修材料。以上所讲的就是紫铜板和黄铜板在组成成分、功用和用处上的差异。紫铜的组成成分比较纯洁，而黄铜还掺杂了其它合金。紫铜板和黄铜板不同的功用使其在用处上也有很大的不同，我们能够依据自己的需求去挑选。         

黄铜板反向揉捏挑选准则   黄铜板反向揉捏挑选的首要准则是:   (1)依据不同金属揉捏时的活动特色(金属活动的四种类型)，能够确认哪些材料应该考虑选用反向揉捏。如:反向揉捏紫铜、黄铜等合金时，金属活动介于A类和B类型之间，揉捏过程中温度与压力的改变很小。选用平棋无光滑反向揉捏铜及铜合金的线材、棒材、型材和管材，关于进步揉捏制品安排功能的均匀性，‘般都是有利的。所以依据金属活动的四种根本类型能够看出:当正向揉捏金属活动呈B,C,D型时.选用反向揉捏才是必要的。   (2)外康擦条件对金属活动有着极为显着的影响，外章攘条件(摩擦系数)不同，则金属活动的类型也不同.所以关于需求进行光滑揉捏的材料，运用反向揉捏较为有利.此刻只需求润清模子的端面。   (3)反向揉捏适用于尺度要求精度高、安排细微面无晶拉环的制品和揉捏沮度规模较窄的合金管、摊、里、线材的揉捏加工。反向揉捏时作用于金属的力，黄铜板反向揉捏时，金属锭坯与揉捏简之间无相对运动，作用于金属上的力。

黄铜板水封揉捏的特色黄铜板水封揉捏具有如下特色: 选用水封揉捏，制品因快速冷却使金属安排晶粒细微，抗拉强度高.延伸好。紫铜非水封揉捏与水封揉捏晶位度对。黄铜板非水封揉捏管坯晶拉均匀直径如表所示。    白钢B3()水封揉捏的晶粒度(高倍安排)如图4-16所示，白B30水封揉捏管坯(制作率95%)晶拉均匀直径如表4-7所示。   (2)黄铜板选用水封揉捏技能对一些合金.如白俐管、黄钢冷凝管等合金会发生必定的影响。因为金属性质的特色，揉捏管坯冷却变形不均匀与急冷变形量大的影响.管坯在水槽中会呈现较大的匆曲现象。能够选用机械装t(如压料辊道、牵引装里等)约束和调整水温的办法来处理。答应水冷的合金列于表.   (3)水封揉捏管材选用封头、尾的工作办法。水封揉捏时为防止管坯内表面氧化和揉捏完了管坯内倒湘水现象，选用封头、封尾揉捏。封头、尾长度一般为80--120 mm,压余别离是用穿孔针顶断办法别离.所以，在实践加工中考虑穿孔针的聋度来挑选水封揉捏的合金和规格范团。    (4)选用水封揉捏技能.水封头前端因为快速通水和排水的速度等原因影响，水封头内会呈现未充溢水而发生空气的现象，导致揉捏完了封尾揉捏时。管坯尾端发生载化，一般长度为300-600 mm。能够依据水封头结构选用水封头内通维护性气体的办法.进行两层维护(现已有运用两层维护水封装工，如带挡板的水封装.    (5)加工中跟着揉捏接连进行.水梢中的水沮不断升高，严格控制循环水且〔一般水沮低于60t),确保揉捏制品表面不发红。循环水运用一段时间后，水箱中的沉淀物变多，黄铜板致使冷却水的清沽度不能确保揉捏制品的表面质量时.应定时替换。

黄铜板揉捏光滑剂的挑选   因为黄铜板揉捏制作具有高沮、高速、高压力等特色，挑选适宜的光滑剂具有特别重要的含义.在挑选揉捏光滑剂时。应该注走以下基本要求:   (1)对尽擦表面尽可能有最大的活性，以确保构成完好、健壮的光滑层。   所谓光滑剂的活性.便是光滑荆中的极性分子在康擦表面构成健壮的保护层才能。光滑剂的猫度越小，活性越小.则光滑层决裂的可能性越大。   (2)有满意的猫度，以使润淆层有满意的厚度。   有必要指出，随漪钻度的添加，一起也会使光滑剂质点的活性下降，所以钻度要恰当.并非越高越好。   (3)对黄铜板揉捏东西及变形金属有必定的化学稳定性.防止腐蚀东西和变形金属表面。    (4)有恰当的闪点，防止在开端揉捏时嫩烧，下降光滑效果。   (5)嫩烧后的灰分要少，并有·定的化学稳定性，削减揉捏制品表里表面的污染。   一般在黄铜板揉捏时，金属表面残留的光滑剂在高沮下会招烧，假如残留下的灰渣较多，又难以去除.特别是与金属起化学反应时，这将使揉捏制品表面质量大大下降。    (6)冷却性能好，对揉捏东西有必定的冷却效果，削减金属活动不均匀性和提离工其的运用寿命。   (7)黄铜板揉捏光滑剂自身发生的气体，不应该对人体和环境发生有害效果.改锌劳动条件。   (8)制作和运用方便，多少钱低廉，成本低。   一般在挑选运用黄铜板揉捏光滑剂时，一些条件和要求住往不能一起满意.能够依据详细加工状况灵敏决议。

黄铜板揉捏力和穿孔力影响揉捏力的各种要素     黄铜板影响揉捏力的要素许多，主要有:金属的变形扰力、变形程度、外冲突状况、模子形状尺度、揉捏模角、揉捏速度、锭坯长度、制品断面形状以及揉捏办法等。变形粗度对揉捏力的影晌    选用不同揉捏比、揉捏不同金属及合金时的揉捏力改变规则变形程度对揉捏力的影响规则   从能够看出，揉捏力与变形程度成正比联系.揉捏力跟着变形程度的增大而升高。几种钥合金的制作率与揉捏力的联系。    从能够看出，揉捏力跟着制作率的添加而添加。揉捏东西对揉捏力的影晌   金属在揉捏东西(揉捏筒、揉捏模)触摸面上的效果，所发生的阻力是揉捏力的组成部分。不同揉捏工其表面状况对揉捏力的影响规则。揉捏工其衷面状况时揉捏力的影响1-粗目面 2-究漪面 3-先淆面井润附   跟着外摩攘阻力的添加.金属活动不均匀程度添加，因此所需的揉捏力添加。能够看出，金属与揉捏筒内衬、揉捏模具表面之间的冲突阻力添加，揉捏力添加。

黄铜板组合揉捏整片的定心效果        黄铜板组合揉捏垫片的首要特点是:将揉捏垫片与整理垫片组合在组合揉捏势片一同，构成揉捏、整理一次完结。运用组合揉捏垫片能够缩短揉捏周期.进步加工效串。别的，在脱皮揉捏中，组合垫片中的消理垫部分还能够起到定心效果，削减揉捏管材的偏疼发生。       因为脱皮揉捏垫片的定心效果.避免垫片移动中带动穿孔针违背中心方位.所以揉捏管材的同心度较好。        为了削减臣夙揉捏机选用穿孔针法揉捏管材时发生偏疼的质量问题，现代揉捏技能中，对黄铜板揉捏东西的规划采取了许多办法.如定心双锥面(梢口)的模支承和揉捏筒内衬、带定位的脱皮揉捏垫片、偏疼模支承等。

黄铜板带水封档板的水封头设备       此装里在揉捏开端前，出料水槽里(挡板后水格)放满水，黄铜板此刻水封头内(挡板与模支承之间)有少童的水，揉捏开端，坯料经过模口进人水封头内并敏捷顶开水封挡板，水柑内的水敏捷充溢水封头内，完成水封揉捏。因为在水封头人口处有一负压区，揉捏完了，制品由牵引辊道拖出后，水不会从模口流出。水封头与出料水格衔接，确保制品挤出后.直接进人水格冷却.使金属不与空气触摸，避免揉捏制品权化。水封装工中的水.靠排水借路与水箱衔接.由油泵作业构成循环活动方法。

黄铜板揉捏比和变形程度的确认         黄铜板揉捏比和变形程度是揉捏进程的两个根本变形参数，这两个参数能够阐明揉捏进程中金属变形最的巨细。在揉捏时，添加变形程度能够使制品的晶拉细化，进步其力学功能。   挑选揉捏进程的变形参数时应考虑以下几点:    (1)黄铜板揉捏速度规模确认后，跟着揉捏比的增大.制品流出模孔的温度与速度均升高.为防止发生揉捏制品的表面粗枯化和揉捏裂纹，应该挑选恰当的揉捏比。    (2)依据揉捏制品的安排与功能要求，为取得较高的力学功能，应尽盆挑选大揉捏比(变形程度)进行揉捏，一般变形程度能够取90%以上，揉捏比不该小于10-120    (3)依据黄铜板揉捏力与揉捏比的对数成正比的联系，最大的揉捏比受揉捏机的揉捏力、揉捏东西强度所约束.挑选揉捏比时，不能超过设备才能。        黄铜板揉捏用于二次揉捏的毛坯.揉捏比能够不限，在揉捏小断面的棒、型材时.为使金属活动均匀.能够选用多模孔揉捏，下降揉捏比。铜及铜合金揉捏比见表。      F—揉捏制品的断面积。

黄铜板实践加工中的其他几种调偏对中技能激光对中技能   选用激光对中装里可准确确认揉捏机中心线，并在揉捏过程中对揉捏轴、穿孔体系、 黄铜板实践加工中的其他几种调偏对中技能揉捏筒和揉捏棋的同心度进行监侧。该设备有激光发射、接纳和检侧信息处理与显现三个部分组成。   实践使用中能够分为两步进行.第一步，是在揉捏机处于原始状况时(设备或检修完成后投人作业前)，在固定横梁上设备激光发射装皿，并在揉捏简两头.揉捏轴和穿孔体系前端等活动部件上设备监侧装。翻开激光发射，各检侧装里接纳信号，经过显现屏显现光束是否处于平衡位里，假如平衡，黄铜板实践加工中的其他几种调偏对中技能则阐明揉捏中心线杰出.假如有问颐可根据检测数据逐个进行调整。第二步，首要撤除原始状况激光装工的设备，将发射设备，检测设备别离设备在揉捏筒支座下部的左右对称位皿和揉捏机活动横梁下部的左右对称位里，并将激光束调至平衡，能够投人加工。     黄铜板实践加工中的其他几种调偏对中技能揉捏开始时，因为揉捏筒(包含揉捏模)、揉捏轴和穿孔体系(穿孔针)，都处于已调好的正确方位，在显现屏上无显现数据。经过一段时间的揉捏作业，经过显现数据来判别各运动部件的方位差错，并能够报据数据调整偏移部件.确保揉捏机处于杰出状况。       我国进口波兰卧式正向揉捏机的激光对中设备的技能参数为:发射波长0.63 5m、能最ImW、电源电压220 V,预率50 Hz、功率50 W、光束直径10一15 mm.接纳装!为圆盘形状，并由四个光电二极管，别离检侧光束在X方向和Y方向的位移并能够显现位移方向，梢度可达10.1mm.激光对中技能首要应用于黄铜板实践加工中的其他几种调偏对中技能揉捏设备各运动部件的对中调整。

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。

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。

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

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

（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。

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）。

检测黄铜管硬度的办法1、黄铜管布氏硬度以必定的载荷（一般3000kg）把必定巨细（直径一般为10mm）的淬硬钢球压入材料表面，坚持一段时间，去载后，负荷与其压痕面积之比值，即为布氏硬度值（HB），黄铜管单位为公斤力/mm2（N/mm2）。2、黄铜管洛氏硬度当HB>450或许试样过小时，不能采用布氏硬度实验而改用洛氏硬度计量。它是用一个顶角120°的金刚石圆锥体或直径为1.59、3.18mm的钢球，黄铜管在必定载荷下压入被测材料表面，由压痕的深度求出材料的硬度。3 、黄铜管维氏硬度 以120kg以内的载荷和顶角为136°的金刚石方形锥压入器压入材料表面，用材料压痕凹坑的表面积除以载荷值，黄铜管即为维氏硬度HV值（kgf/mm2）。
