Cast aluminum alloys are divided into four categories according to the main elements other than aluminum in the composition: silicon, copper, magnesium, and zinc. The code codes are:,,,. In order to obtain high-quality precision castings of various shapes and specifications, the aluminum alloys used for casting generally have the following characteristics. It has good fluidity in the narrow gap part with filled slots. It has a lower melting point than ordinary metals but can meet the requirements of most situations. It has good thermal conductivity. The heat of the molten aluminum can be quickly transferred to the mold. The casting cycle is short. Hydrogen and other gases in the melt are Harmful gases can be effectively controlled through treatment. There is no tendency for hot brittle cracking and tearing during aluminum alloy casting. It has good chemical stability and strong corrosion resistance and is not prone to surface defects. The surface of the casting has good surface finish and gloss and is easy to surface treat. Cast aluminum The alloy has good processing properties and can be cast using die molds, hard molds, green and dry sand molds, and investment plaster casting molds. Vacuum casting, low-pressure and high-pressure casting, squeeze casting, semi-solid casting, centrifugal casting and other methods can also be used. Forming and production of various castings with different uses, varieties and specifications, and different properties. Cast aluminum alloys are widely used in cars, such as engine cylinder heads, intake manifolds, pistons, wheel hubs, steering booster housings, etc.
