Cu-OF C10200铜合金断后伸长率

 Cu-OF C10200铜合金断后伸长率

以锡为主要合金元素的青铜。含锡量一般在3～14%之间，主要用于制作弹性元件和耐磨零件。变形锡青铜的含锡量不超过 8%，有时还添加磷、铅、锌等元素。磷是良好的脱氧剂，还能改善流动性和耐磨性。锡青铜中加铅可改善可切削性和耐磨性，加锌可改善铸造性能。这种合金具有较高的力学性能、减磨性能和耐蚀性，易切削加工，钎焊和焊接性能好，收缩系数小，无磁性。可用线材火焰喷涂和电弧喷涂制备青铜衬套、轴套、抗磁元件等涂层。尺寸规格有Ф1.6mm、Ф2.3mm。具有较高的强度、耐蚀性和优良的铸造性能，长期以来广泛应用于各工业部门中。

(1)锡青铜以锡为主要合金元素的铜基合金称锡青铜。工业中使用的锡青铜，锡含量大多在3%～14%之间。锡含量小于5%锡青铜适于冷加工使用;锡含量为5%～7%的锡青铜适于热加工;锡含量大于10%的锡青铜适于铸造。

锡青铜在造船、化工、机械、仪表等工业中广泛应用，主要用以制造轴承、轴套等耐磨零件和弹簧等弹性元件以及抗蚀、抗磁零件等。
