Main applications of aluminum and magnesium alloys die casting parts

2022.04.07  Share Page +

Casting is most often used for making complex shapes that would be difficult or uneconomical to make by other methods.

High-pressure die casting (HPDC) is a very popular process for making complex mechanical parts out of light metals like aluminum and magnesium alloys. It is capable of rapidly producing parts with high dimensional accuracy. HPD growth paralleled that of the automobile industry, where the demands of assembly line manufacture spurred the demand for a quick, reliable way to make components. With the growth ofJIT manufacturing, the automobile industry continues to be the dominant user of HPDC parts. Other end uses for die casting include recreational vehicles, power tools, electrical machinery, electronic components and housewares.

Pure magnesium has a density of about two-thirds of aluminum and one-fourth of iron. It also has good vibration damping, dent resistance, machinability and provides shielding against electromagnetic waves. However, it also has shortcomings like insufficient strength, poor elongation and heat resistance and vulnerability to corrosion.Many of these limitations have been overcome through the development of special alloys.
