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主要添加元素的名。錫青銅的鑄造性能﹑減摩性能好和機械性能好﹐適合於制造軸承﹑蝸輪﹑齒輪等。鉛青銅是現(xiàn)代發(fā)動機和磨床廣泛使用的軸承材料。鋁青銅強度高﹐耐磨性和耐蝕性好﹐用於鑄造高載荷的齒輪﹑軸套﹑船用螺旋槳等。 CA104 CW307G CuAl10Ni C63200 C63000? e AB1-C CC331G CuAl10Fe2-C C95400 SAE68?AB2-C CC333G CuAl10Fe5Ni5-C C95500 SAE68B Leaded Bronze LB1-C CC496K CuSn7Pb15-C C93800 SAE67?
