锡对纯铜电车线性能的影响

Effects of Sn on the Properties of Pure Copper Electric Train Wire

对加入不同锡量的纯铜试样的强度、硬度、导电性和耐磨性等进行了测定。结果表明,锡的加入能细化晶粒,提高纯铜电车线的强度、硬度、耐磨性,但降低其导电性。锡的最佳加入量为0.2%。

The strength,hardness and conductive property of Cu-Sn alloy specimen containning different doses of Sn was tested.The experimental result shows that strength,hardness of electric-train wire of copper alloy,but devaluat its conductive property.The best added dose of Sn is about 0.2 percent.
