4000 series generally has a silicon content between 4.5% and 6%, and the higher the silicon content, the higher the strength. Its melting point is low, and it has good heat resistance and wear resistance. It is mainly used in building materials, mechanical parts, etc.

5000 series, with magnesium as the main element, can also be referred to as magnesium aluminum alloy. Commonly seen in industry, it has low density, high tensile strength, and good elongation.

6000 series, with magnesium and silicon as the main elements, concentrate the characteristics of four series and five series, suitable for scenarios with high corrosion and oxidation.

7000 series, mainly containing zinc element, also belongs to aviation aluminum material, can be heat treated, belongs to superhard aluminum alloy, and has good wear resistance.

8000 series, which is an alloy system other than the above, belongs to other series and is mostly used for aluminum foil production.
