普通性能
紫銅是比較純凈的一種銅,一般可近似認(rèn)為是純銅,導(dǎo)電性、塑性都較好,但強度、硬度較差一些。紫銅具有優(yōu)良的導(dǎo)熱性﹑延展性和耐蝕性。紫銅中的微量雜質(zhì)對銅的導(dǎo)電、導(dǎo)熱性能有嚴(yán)重影響。其中鈦、磷、鐵、硅等顯著降低電導(dǎo)率,而鎘、鋅等則影響很小。硫、硒、碲等在銅中的固溶度很小,可與銅生成脆性化合物,對導(dǎo)電性影響不大,但能降低加工塑性。
紫銅在大氣、海水和某些非氧化性酸(鹽酸、稀硫酸)、堿、鹽溶液及多種有機酸(醋酸、檸檬酸)中,有良好的耐蝕性,用于化學(xué)工業(yè)。另外,紫銅有良好的焊接性,可經(jīng)冷、熱塑性加工制成各種半成品和成品。20世紀(jì)70年代,紫銅的產(chǎn)量超過了其他各類銅合金的總產(chǎn)量。
