在我们的生活当中，大家应该都知道铜是比较贵重的一种材料，因为铜是属于比较稀.缺一种的，所以导致它的价格特别的高昂。而铜的种类也有很多种，比如红铜。可能大家对红铜的认知过少，所以不清楚什么是红铜。钣金加工一般会用到红铜与黄铜材质的板材，那究竟怎样区分黄铜和红铜，今天就由南阳钣金定制小编来为大家详细的讲(jiang)解一(yi)下。

红铜即纯铜，又名紫(zi)铜，具有很好(hao)导(dao)电(dian)(dian)性和(he)导(dao)热性，塑(su)性好(hao)，易于(yu)热压(ya)和(he)冷压(ya)力(li)加工，大量用(yong)于(yu)制(zhi)造电(dian)(dian)线、电(dian)(dian)缆(lan)、电(dian)(dian)刷、电(dian)(dian)火花(hua)专用(yong)电(dian)(dian)蚀(shi)铜等(deng)要(yao)求导(dao)电(dian)(dian)性良好(hao)产品(pin)。

黄铜(tong)(tong)由铜(tong)(tong)和锌(xin)所组成合(he)金。如(ru)果只是由铜(tong)(tong)、锌(xin)组成黄铜(tong)(tong)就叫作(zuo)普通(tong)黄铜(tong)(tong)。如(ru)果是由二种(zhong)以上元素组成多种(zhong)合(he)金就称为特殊黄铜(tong)(tong)。

红铜跟黄铜怎么(me)分别？

1、自(zi)然(ran)界中有一(yi)定(ding)数量(liang)的自(zi)然(ran)铜(tong)存在。未经人工羼杂其它(ta)物质的自(zi)然(ran)铜(tong)，即纯铜(tong)，也称(cheng)红铜(tong)，它(ta)具(ju)有一(yi)定(ding)的金属光泽和延展性(xing)，很容(rong)易被人们重视和利用。

2、黄铜(tong)是(shi)铜(tong)与锌的合金。简单(dan)的黄铜(tong)是(shi)铜(tong)——锌二元合金，称为(wei)简单(dan)黄铜(tong)或普通黄铜(tong)

3、紫铜(tong),又叫红铜(tong),即(ji)纯铜(tong)

4、红(hong)铜和(he)黄(huang)铜在颜色(se)和(he)质量(liang)上都(dou)是有区别(bie)的!其(qi)实颜色(se)一看就明白,顾(gu)名(ming)思义!质量(liang)上红(hong)铜要比(bi)黄(huang)铜硬一些,重量(liang)差不多(duo)!

5、红铜具有良好的热(re)电导性(xing)(xing)(xing)、加工性(xing)(xing)(xing)、延展性(xing)(xing)(xing)、防蚀性(xing)(xing)(xing)等特点。黄铜有较强的耐(nai)磨性(xing)(xing)(xing)能。

区分方法

1、物(wu)理方法：黄(huang)铜(tong)：金(jin)属黄(huang)色(se)或者(zhe)偏暗黄(huang)色(se)，铜(tong)跟锌合(he)金(jin)，比紫(zi)铜(tong)坚硬(ying)得多，主要用于锻造件(jian)，比如水龙头(tou)等(deng)

紫(zi)铜(tong)：又称(cheng)红(hong)铜(tong)，铜(tong)，红(hong)铜(tong)也称(cheng)紫(zi)铜(tong)，杂质很少(shao)，接近纯铜(tong)，韧(ren)(ren)性、延展性都好；黄铜(tong)铜(tong)中含(han)(han)少(shao)量锌(xin)。韧(ren)(ren)性、延展性差(cha)，硬度(du)高；青铜(tong)含(han)(han)锡(xi)，或含(han)(han)铍等，种类较多，耐磨。

2、化学(xue)方法：将黄铜(tong)(tong)(tong)(tong)和(he)(he)(he)红铜(tong)(tong)(tong)(tong)分别取样,加入盐(yan)酸(suan)(suan),黄铜(tong)(tong)(tong)(tong)会冒气(qi)泡(pao),红铜(tong)(tong)(tong)(tong)几乎不冒气(qi)泡(pao)，黄铜(tong)(tong)(tong)(tong)由(you)(you)铜(tong)(tong)(tong)(tong)和(he)(he)(he)锌所组(zu)成(cheng)合金(jin)(jin).如果只是由(you)(you)铜(tong)(tong)(tong)(tong)、锌组(zu)成(cheng)黄铜(tong)(tong)(tong)(tong)就叫作普通黄铜(tong)(tong)(tong)(tong).黄铜(tong)(tong)(tong)(tong)常被(bei)(bei)用于(yu)(yu)制造阀(fa)门、水(shui)管、空调内外机连接管和(he)(he)(he)散热(re)器等(deng)。红铜(tong)(tong)(tong)(tong)即(ji)纯铜(tong)(tong)(tong)(tong),又名紫铜(tong)(tong)(tong)(tong),具有很(hen)好(hao)导(dao)电性和(he)(he)(he)导(dao)热(re)性,塑性好(hao),易于(yu)(yu)热(re)压和(he)(he)(he)冷(leng)压力加工,大量用于(yu)(yu)制造电线、电缆、电刷、电火花(hua)专用电蚀(shi)(shi)铜(tong)(tong)(tong)(tong)等(deng)要求导(dao)电性良好(hao)产品，铜(tong)(tong)(tong)(tong)和(he)(he)(he)它一些合金(jin)(jin)有较好(hao)耐腐(fu)蚀(shi)(shi)能(neng)力,干燥空气(qi)里(li)很(hen)稳定(ding).但在潮(chao)湿空气(qi)里(li)在其表(biao)面可(ke)以(yi)生成(cheng)一层绿色碱式碳酸(suan)(suan)铜(tong)(tong)(tong)(tong)Cu2（OH）2CO3,这叫铜(tong)(tong)(tong)(tong)绿.可(ke)溶(rong)于(yu)(yu)硝酸(suan)(suan)和(he)(he)(he)热(re)浓硫酸(suan)(suan),略溶(rong)于(yu)(yu)盐(yan)酸(suan)(suan).容(rong)易被(bei)(bei)碱侵(qin)蚀(shi)(shi)。
