锡青铜有优良的铸造性能,收缩性小不易产生集中缩孔,因此浇冒口设计较无锡青铜及黄铜简单,即青铜有良好的耐磨性,适合制造磨擦的零件如轴承等.一般认为锡青铜有树枝状结晶的多孔性,不能承受较高的水压试验,但是如果熔化过程和浇注系统采用适当,也可以得到耐水压试验的铸件.锡青铜旧料回收综合使用 Tin bronze has excellent casting performance, shrinkage is not easy to produce concentrated shrinkage hole, so pouring riser design than Wuxi bronze and brass is simple, that is, bronze has good wear resistance, suitable for the manufacture of friction parts such as bearings, etc. Generally believed that Tin bronze has dendritic crystal porosity and can not withstand higher hydrostatic tests, but hydrofluorocarbon castings can also be obtained if proper melting and pouring systems are used.
