At present, aluminum materials are widely used. They are relatively lightweight, have low rebound during forming, have strength similar to steel, and have good plasticity. They have good thermal conductivity, conductivity, and corrosion resistance. The surface treatment process of aluminum materials is also very mature, such as anodizing, wire drawing, and so on.

The aluminum and aluminum alloy codes on the market are mainly divided into eight series. Below is a detailed understanding of their characteristics.

1000 series, it has the highest aluminum content among all series, with a purity of over 99%. The surface treatment and formability of a series of aluminum are very good, with the best corrosion resistance compared to other aluminum alloys, but slightly lower strength, mainly used for decoration.

2000 series is characterized by high strength, poor corrosion resistance, and the highest copper content. It belongs to aviation aluminum materials and is commonly used as a construction material. It is relatively rare in conventional industrial production.

3000 series, mainly composed of manganese element, has good rust prevention effect, good formability and corrosion resistance. It is commonly used in the production of tanks, tanks, various pressure vessels and pipelines for containing liquids.
