国外,在有色金属各种合金的冶炼中广泛地应用稀土。稀土被有效地用于铜、镍、铝、镁、钛、钒、铌、铬、钨合金和其它一系列有色金属的合金化,并用作金属热反应的强还元剂。稀土对有色金属基合金都有着良好的影响,能够改善合金的物理性能和机械性能。有色金属中添加稀土的含量范围很宽,约0.001～0.5到8～10％之间。加入适量的稀土可以得到重量轻而强度高的合金,这些合金可以用来制造航空、火箭、汽轮机和发动机零件等。有许多添加稀土的有色金属产品已经纳入标准化系列,并且订出比较合理的价格。
Abroad, rare earths are widely used in the smelting of various non-ferrous metals. Rare earth is effectively used for the alloying of copper, nickel, aluminum, magnesium, titanium, vanadium, niobium, chromium, tungsten alloys and other series of non-ferrous metals and as a strong replenisher for the thermal reaction of metals. Rare earth has a good effect on non-ferrous metal-based alloys, can improve the physical and mechanical properties of the alloy. Non-ferrous metals added to the range of rare earth content is very wide, about 0.001 ~ 0.5 to 8 ~ 10% between. Adding the right amount of rare earths results in lightweight and high strength alloys that can be used to make aerospace, rockets, steam turbines and engine components. There are many non-ferrous metals added rare earth products have been standardized into the series, and set a more reasonable price.
