铜合金

Sulfide ores with BaSO4 as the main gangue , two kinds of slags , speiss and As-Cu alloy have been identified.

还原熔炼中添加了矿物，冶炼的最终产品是合金，还原熔炼产生的（黄渣）等副产品中的通过返料操作熔炼工序以回收。

It is concluded that the new Mn-Cu alloy is feasible to be used as absorber in the high-speed rotary fusee-testing machine by the experiment.

通过实验测新型锰合金适合作为高速旋转设备减振部件的结论。
