叙述了新合金 (稀土锰黄铜ZHMn5 8- 3.5 - 2 - 0 .0 15 )代替锡青铜ZQSn6 - 6 - 3作轴承材料的可行性 ,以及新合金的性能测试 ,并与锡青铜作了比较 ,分析得出新合金在机械性能、化学性能等方面都能代替锡青铜 ,仅在物理性能 (线膨胀系数 )方面不够理想 ,有待进一步研究 The feasibility of using new alloy (rare earth manganese brass ZHMn5 8 - 3.5 - 2 - 0. 0 15) instead of tin bronze ZQSn6 - 6 - 3 as bearing material and the performance testing of new alloy are described and compared with tin bronze , The analysis shows that the new alloy can replace tin bronze in terms of mechanical properties and chemical properties and is not ideal only in terms of physical properties (coefficient of linear expansion), and needs further study
