青銅原指銅錫合金﹐后除黃銅﹑白銅以外的銅合金均稱青銅﹐并常在青銅名字前冠以di1主要添加元素的名。錫青銅的鑄造性能﹑減摩性能好和機(jī)械性能好﹐適合於制造軸承﹑蝸輪﹑齒輪等。鉛青銅是現(xiàn)代發(fā)動(dòng)機(jī)和磨床廣泛使用的軸承材料。鋁青銅強(qiáng)度高﹐耐磨性和耐蝕性好﹐用于鑄造高載荷的齒輪﹑軸套﹑船用螺旋槳等。磷青銅的 性很限高﹐導(dǎo)電性好﹐適於制造精密 簧和電接觸元件﹐鈹青銅還用來(lái)制造煤礦﹑油庫(kù)等使用的無(wú)火花工具。鈹銅是一種過(guò)飽和固溶體銅基合金，是機(jī)械性能，物理性能，化學(xué)性能及抗蝕性能良好；粉末冶金制作針對(duì)鎢鋼，高碳鋼、耐高溫超硬合金制作的模具需電蝕時(shí)，因普通電很損耗大，速度慢，鎢銅是比較理想材料?？箯潖?qiáng)度≥667Mpa。
