Knowledge

In aluminum alloy grade is representative significance, the following on the 7075T651 aluminum plate grade as an example to illustrate. The first 7 indicates aluminum and aluminum alloy Group-aluminum zinc magnesium alloy. Aluminium and aluminum alloy groups are divided into nine categories.

Among them, 1, 3, 5, 6, 7 Series of aluminum, aluminum alloy mainly, other families in the actual use of the use of less chance.

Category 1: 1 Series: Industrial Pure Aluminum

Category 2: 2 Series: Aluminium copper alloy

Category 3: 3 Series: Aluminum Manganese alloy

Category 4: 4 series: Aluminum Silicon alloy

Category 5: 5 Series: Aluminum Magnesium alloy

Category 6: 6 Series: Aluminum Magnesium silicon alloy

Category 7: 7 Series: Aluminium Zinc magnesium Copper alloy

Category 8: 8 Series: Other alloys Category nineth: 9 Series: Spare alloys
