What are the Uses of Aluminum Series Alloys 1, 2, 3, 5, 6, and 7?

1 series: It belongs to the series with the largest amount of aluminum. The purity can reach above 99.00%. For conventional industries

2 series: high hardness, with the highest content of copper, about 3-5%, for aviation

3 series: The main component is manganese. The content is between 1.0-1.5, which is used in industries and products with high anti-rust requirements.




5 series: It belongs to the more common alloy aluminum plate series. The main element is magnesium. The main features are low density, high tensile strength, high 

elongation and good fatigue strength, but it cannot be heat treated. It is also widely used in conventional industries.


6 series: mainly contains magnesium and silicon, suitable for applications requiring high corrosion resistance and oxidation resistance.

7 series: belongs to the aviation series, is aluminum magnesium zinc copper alloy, is a heat treatable alloy, belongs to super hard aluminum alloy, has good wear 

resistance, also has good weldability, but has poor corrosion resistance.
