In recent years, as a new high-quality material, aluminum alloy is favored by more users and gradually replaces traditional materials in many fields. Among the 1-8 series aluminum alloys, 5 series aluminum magnesium alloys are particularly widely used. Among them, 5454 aluminum plate and 5182 aluminum plate are representative products. Both of them have medium strength, good corrosion resistance, processability and weldability. But there are many differences.
The main alloy elements of 5454 aluminum plate and 5182 aluminum plate are magnesium, and the essential difference between them lies in the composition and content of alloy elements. The content of magnesium and manganese in 5182 is more than that of 5454, and there are some differences in performance and application.
5454 aluminum alloy:
Silicon Si: ≤ 0.25
Copper Cu: ≤ 0.10
Mg: 2.4 ~ 3.0
Zinc Zn: ≤ 0.25
Mn: 0.50 ~ 1.0
Titanium Ti: ≤ 0.20
Cr: 0.05 ~ 0.20
Fe: 0.000 ~ 0.400
Al: allowance
5182 aluminum plate alloy:
Zinc Zn: ≤ 0.25
Cr: ≤ 0.10
Silicon Si: ≤ 0.20
Fe: 0.000 ~ 0.350
Mn: 0.20 ~ 0.50
Mg: 4.0 ~ 5.0
Titanium Ti: ≤ 0.10
Copper Cu: ≤ 0.15
Al: allowance
Not only that, they are also used for different purposes. 5454 aluminum sheet metal is used in welded structures, pressure vessels, offshore facilities and pipelines. 5182 aluminum plate, thick plate and thin plate are widely used. The thin plate is used to process can covers, automobile body panels, control panels, stiffeners, brackets and other parts.
