黄铜和紫铜的区别
黄铜和紫铜的区别如下
1、颜色不同
黄铜呈淡金黄色,有光泽;紫铜呈玫瑰红色,有光泽。
2、用途不同
黄铜铸件常用来 *** 阀门和管道配件等。普通黄铜的用途极为广泛,如水箱带、供排水管、奖章、波纹管、蛇形管、冷凝管、弹壳及各种形状复杂的冲制品、小五金件等。
有良好的导电,导热性能及抗蚀,有韧性,紫铜富有延展性,紫铜导电性能好,在的金属中仅次于银,但铜比银得多,因此成了电气工业的“主角”。
3、含铜量不同
紫铜,铜的含量达到了99.9%;黄铜,铜60%左右,锌40%左右;个别含铅1%左右,是有杂质的。
紫铜和黄铜的区别
紫铜和黄铜的区别如下:
1、外观上的不同
紫铜的颜色是玫瑰红色的,黄铜的颜色一般是金黄色的。
2、成分上的不同
紫铜的成分主要就是铜,但是黄铜的成分有铜还有锌。
3、强度上的不同
紫铜的成分主要就是铜,基本没有其它的杂质,因此紫铜的强度相对来说是比较低的,黄铜的成分比较多,因此黄铜的强度一般是比较高的。
4、密度上的不同
紫铜的密度是在8.9-8.95,黄铜的密度是在8.52-8.62。
5、延展性
紫铜延展性较好,黄铜的延展性较紫铜的延展性差。
6、耐蚀性
紫铜的耐蚀性较好,黄铜的耐蚀性较差。
7、导电率
紫铜的导电,黄铜的导电率较低。
8、切割性能
紫铜的切割性能较差,黄铜的切割性能较好。
紫铜是一种紫红色有光泽的金属,因为是玫瑰红色,表面形成氧化膜后呈紫色,所以被称为紫铜。黄铜是由锌和铜所组成的一种合金,一般由锌和铜组成的黄铜叫普通黄铜,两种以上的元素组成的黄铜称为特殊黄铜。
紫铜和黄铜的区别是什么 如何区别紫铜和黄铜
1、外观不同,外观不同是紫铜和黄铜的主要区别之一,紫铜顾名思义是外观呈现紫红色、玫瑰红色的铜金属,而黄铜顾名思义是外观可以呈现出淡金黄色的铜金属。
2、密度不同,此外紫铜和黄铜的区别还在于密度不同,紫铜的密度在8.9~8.95之间,而黄铜的密度在8.52~8.62之间。因此紫铜的密度会相对更大,同体积的紫铜和黄铜相比,紫铜的压手感更强烈。
3、成分不同,从紫铜和黄铜的成分来看,紫铜中的铜金属含量为50%左右,而黄铜中的铜元素含量在60%左右,此外还含有40%左右的锌元素,个别品牌的黄铜还会含有1%左右的锌。
紫铜和黄铜的区别是什么?
1、成分的不同
紫铜:主成分为铜加银,含量为99.7~99.95%;主要杂质元素是磷、铋、锑、砷、铁、镍、铅、锡、硫、锌、氧等。
黄铜:黄铜是由铜和锌所组成的合金。
2、性质不同
紫铜:紫铜在大气、海水和某些非氧化性酸(盐酸、稀 *** )、碱、盐溶液及多种有机酸(醋酸、柠檬酸)中有良好的耐蚀性。
黄铜:强度高、硬度大、耐化学腐蚀性强。
3、用途不同
紫铜:主要用于 *** 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。
黄铜:制造阀门、水管等。
