　　鋁合金外殼的選擇要根據具體的用途而定，同時還要考慮到產品的成本、壽命和使用環境等因素。

　　An aluminum alloy shell refers to the common computer shell and other electronic products in daily life. It is made of aluminum alloy as the main material, so it has strong wear resistance and good heat dissipation performance. The advantages of aluminum alloy shell are as follows: high strength, low density, good corrosion resistance, good thermal conductivity, easy processing, easy plastic spraying, easy galvanizing, and smooth surface.

　　Because of its good gloss, aluminum alloy shells are often used in the manufacture of high-end precision instruments, such as medical equipment, TV sets, etc. Nowadays, it is also widely used in household appliances, automobiles, communication equipment, industrial automation equipment, etc.

　　The main components of aluminum alloy shell are aluminum, magnesium, manganese, copper, zinc, tin, antimony, chromium, titanium, barium, strontium, etc. The chemical composition ratio and structural composition have a direct impact on the product performance.

　　According to the different uses of aluminum alloy shells, they can be divided into industrial aluminum alloy shells, automotive aluminum alloy shells, household appliance aluminum alloy shells, three-dimensional shells, etc.

　　Different aluminum alloy shell materials have different characteristics. Below we introduce the characteristics of common aluminum alloy shell materials.

　　Aluminum magnesium alloy shell has good corrosion resistance and good impact resistance and tensile strength, so it is widely used in industry and automobile industry.

　　Magnesium aluminum alloy shell has excellent corrosion resistance and good thermal conductivity and impact resistance, so it is widely used in the manufacture of electronic products.

　　Magnesium manganese alloy shell has excellent corrosion resistance and good impact resistance, so it is widely used in communication equipment, household appliances and automobile industry.

　　Zinc titanium alloy shell has excellent corrosion resistance and good impact resistance, so it is widely used in electronic products, household appliances and automobile industry.

　　Nickel manganese alloy shell has excellent corrosion resistance and good impact resistance, so it is widely used in electronic products, household appliances and automobile industry.

　　Aluminum alloy shell selection should be based on specific use, but also take into account the cost, life and use of products and environmental factors.
