Casting aluminum alloys is mainly to improve the mechanical properties of the metal and is distinguished according to its main alloying elements: magnesium and magnesium. Alloy substances that exceed the melt's degree of purity are pure, or they are common and interphase.
Silicon can improve the castability of aluminum. In co-alloys such as ANS12, a small amount of A is first added, and then the eutectic is refined by casting. During this refining process, silicon will not be deposited as needles or flake crystals, but It forms a very thin band. The hardening effect of these alloys is very low, so magnesium is added to enable age hardening.
Cast alloys with specific properties are used in a wide range of products, including the production of pistons, plain bearings, mechanical engineering parts, cylinder heads and brake shoes.
