A Brief Discussion on the Processing Technology of Aluminum Alloy

Pure aluminum has a low density, about 1/3 of iron, and a low melting point. Aluminum is a face-centered cubic structure, so it has high plasticity and is easy to process. It can be made into various profiles and plates with good corrosion resistance; but the strength of pure aluminum is very low, so it is not suitable for structural materials. Through long-term production practice and scientific experiments, people gradually strengthened aluminum by adding alloy elements and using heat treatment methods, which resulted in a series of aluminum alloys. The alloy formed by adding certain elements can have high strength while maintaining the advantages of pure aluminum such as light weight. This makes its "specific strength" better than many alloy steels, making it an ideal structural material. It is widely used in machinery manufacturing, transportation machinery, power machinery and aviation industry. The fuselage, skin, compressor, etc. of aircraft are often made of aluminum alloy to reduce their own weight. The use of aluminum alloy instead of steel plate material welding can reduce the weight of the structure by more than 50%.

With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum alloy structural parts has increased, which has led to in-depth research on the processing of aluminum alloys. The wide application of aluminum alloys has promoted the development of aluminum alloy processing technology. At the same time, the development of processing technology has expanded the application field of aluminum alloys. Therefore, aluminum alloy processing technology is becoming one of the hot spots of research.
