How many types of aluminum are there?

Series 1 (representing pure aluminum, containing no less than 99% aluminum) : belongs to a series containing the most aluminum. For conventional industry

2 series (mainly copper alloy) : high hardness, of which the highest content of copper, about 3-5%, used in the aviation field

3 series (mainly with manganese) : the content is between 1.0-1.5, used in industries and products with high requirements for rust prevention

Series 4 (mainly silicon) : content between 4.5-6.0%. Construction materials, mechanical parts, forging materials, welding materials; Low melting point, good corrosion resistance, heat resistance, wear resistance.

5 series (mainly magnesium) : belongs to the more commonly used alloy aluminum plate series, the main characteristics are low density, high tensile strength, high elongation, good fatigue strength, but can not be strengthened by heat treatment. It is also widely used in conventional industry.

6 series (mainly magnesium and silicon) : mainly contains magnesium and silicon two elements, suitable for corrosion resistance, oxidation requirements of high applications.

7 series (mainly zinc) : belongs to the aviation series, is aluminum magnesium zinc copper alloy, is heat treatable alloy, belongs to super hard aluminum alloy, has good wear resistance, also has good weldability, but poor corrosion resistance.

8 series (Other elements)
