新研制的无镍高锰铝青铜具有优良的综合机械性能和耐磨性能。这种耐磨铜合金材料可以代替普通的铝青铜和含镍高锰铝青铜,适合于制造在高负荷、冲击及中温(400℃)下工作的耐磨零件,如薄板热轧机轴瓦,也适合于制成在室温下工作的其它耐磨零部件。合金中添加了少量稀土金属和硼,这对改善合金的结晶组织、机械性能、铸造性能和耐磨性能都有明显的作用。
Newly developed nickel-free high manganese aluminum bronze has excellent mechanical properties and wear resistance. This wear-resistant copper alloy can replace ordinary aluminum bronze and nickel-containing high manganese aluminum bronze and is suitable for the manufacture of wear-resistant parts such as sheet hot-rolling mill bearings operating under high loads, shocks and medium temperatures (400 ° C) It is suitable for other wear-resistant parts that work at room temperature. Adding a small amount of rare earth metals and boron alloy, which improve the crystal structure of the alloy, mechanical properties, casting performance and wear resistance have a significant role.
