1. Introduce
– A lightweight metal that is fairly soft among metals and has about one-third the specific gravity of iron
– Low temperature strength metal that can be used at temperatures as low as -200℃
– A strong nitrogen oxide with a strong affinity for oxygen and nitrogen
– A very chemically reactive metal that resists corrosion from air and water due to the thin oxide film that naturally forms on its surface
– Al alloy element influence : the role of deoxidation and grain refinement, improve the impact toughness of steel, Reduce cold brittleness and aging tendency, improve the corrosion resistance of steel
2. Property
– Ductility, malleability, thermal and electrical conductivity, corrosion resistance, strength, specific strength, tensile strength, machinability, good low temperature strength
