硅黄铜易切削性的研究

Research on Free-Cutting for Silicon Brass

本文主要研究了以廉价的半金属元素硅,替代有毒的铅和比较昂贵的铋、锑、碲等元素,以获得新型环保铜合金材料。通过实验得出了各种硅含量对合金的拉伸性能和切削性能的影响,得出实验最佳的硅的添加量。

This paper made a special study of replacing poisonous lead and expensive bismuth、antimony、tellurium by silicon to gain a new copper alloy material.Through experiment,it obtained silicon contentand silicon increasing amount.
