航空工业部是我国稀土开发应用起步较早的单位。50年代起稀土镁合金开始用于飞机蒙皮、发动机、壳体及其他非受力部件。随着我国稀土工业的发展,稀土在航空材料中的应用日益广泛,目前稀土材料及其产品已在强击机、歼击机、直升机、民航机及无人驾驶飞机都有不同程度的应用。不仅提高了产品性能,而且取得了良好的技术经济效益。
Aviation Industry Department is China’s rare earth development and application of an earlier unit. Since the 1950s rare earth magnesium alloy began to be used for aircraft skin, engine, shell and other non-stressed parts. With the development of China’s rare earth industry, the application of rare earth in aviation materials is increasingly widespread. At present, rare earth materials and their products have been used to varying degrees in attack planes, fighter planes, helicopters, civil aircraft and unmanned aircraft. Not only improve the product performance, but also achieved good technical and economic benefits.
