Rare earth application in aluminium alloy

Rare earth is effective additives in metallurgical industry, rare earth metal has the very high chemical activity, low potential and special black silicon carbides shell structure, almost can react with all elements. Rare earth resources in China is very rich, complete varieties, good quality, wide distribution, mining and convenient. Has proven reserves of rare earths, of t, accounting for 80% of the world's reserves, the world in the first place. In recent years,
Rare earths in metallurgy, machinery, petrochemical industry, electronic, atomic energy, medical, agriculture, aviation and defense Brown Corundum and other fields has been widely used. Rare earth started relatively late in the application of aluminum and its alloys, abroad began in the 1930 s, China began in ShangShi 60 s, but develops very fast, especially in the role of aluminum and its alloys and applied research has achieved obvious effect. This is mainly concentrated in the silicon al-si casting alloy, aluminum and magnesium (zinc) deformation aluminium alloy, aluminium alloy wire and piston alloy, etc. The influence of rare earth on aluminium and its alloy regularity and mechanism research has made some progress.
