红铜
纯铜,又名紫铜,具有很好的导电性和导热性,塑性极好,易于热压和冷压力加工,大量用于制造电线、电缆、电刷、电火花专用电蚀铜等要求导电性良好的产品。
即赤铜。由硫化物或氧化物铜矿石冶炼得来的纯铜,可用以铸钱及制作器物。 明 宋应星 《天工开物·铜》:“凡铜供世用,出山与出炉,止有赤铜。以炉甘石或倭铅参和,转色为黄铜;以砒霜等药制炼为白铜;矾、硝等药制炼为青铜;广锡参和为响铜;倭铅和写﹝泻﹞为铸铜。初质则一味红铜而已。” 郭沫若 《中国史稿》第一编第三章第二节:“他们冶炼的红铜成分很纯,除天然的微量(0.1 -0.2%)杂质外,没有人工加入锡或铅使成合金。红铜的硬度虽较差,但直接经过捶打就能制成各种工具和装饰品。”
特性:高纯度,组织细密,含氧量极低。无气孔、沙眼、疏松,导电性能极佳,电蚀出的模具表面精度高,经热处理工艺,电极无方向性,适合精打,细打,具有良好的热电道性、加工性、延展性、防蚀性及耐候性等。
用途:可应用于电器、蒸溜建筑及化学工业,尤其端子印刷电器路板,电线遮蔽用铜带、气垫,汇流排端子。电磁开关、笔筒、屋根板等。
