How to distinguish the alloy grade of aluminum alloy?

As a well-known supplier of aluminum products in China, Huawei Aluminum can provide customers with high-quality aluminum sheets, aluminum coils, aluminum strips, aluminum discs, aluminum foil and other products;
As a supplier of aluminum products, many of the orders we receive are products with special specifications and special alloys, such as 3003 5005 aluminum plate, 4×8 aluminum sheet, 1000mm x 2000mm 5052 aluminum sheet, etc.;
So, can we use the naked eye to distinguish the grade of aluminum alloy? The answer is clearly no;
According to the alloy grade, aluminum alloy can be divided into 1 series aluminum alloy (1050, 1060, 1070, 1100);
3 series aluminum alloy, 3003 aluminum, 3004 aluminum, 3103 aluminum, 3104 aluminum;
5 series aluminum alloy, 5005 aluminum plate, 5052 aluminum plate, 5083 aluminum plate, 5086 aluminum plate, 5754 aluminum plate, etc.;
6 series aluminum alloy, 6061 aluminum, 6083 aluminum, etc.;

5052-H32 aluminum plate

With so many aluminum alloy grades, their general appearance is similar, but there will be great differences in chemical composition, physical and chemical properties, but their main component is still aluminum;
Due to the high aluminum content of the 1 series aluminum alloy, the aluminum alloy of this alloy grade is equivalent to a pure aluminum plate, and the texture is relatively soft;
The 3-series aluminum alloy is based on the 1-series pure aluminum with the addition of mn elements to improve the hardness of the aluminum alloy;
The 5-series aluminum alloy is an Al-Mg alloy, which has strong corrosion resistance in addition to the strength of the 3-series aluminum alloy;
The 6 series aluminum alloy contains a large amount of Mg2Si, which can improve the corrosion resistance of the alloy to a certain extent;
Aluminum alloy grades cannot be distinguished from the appearance. To distinguish aluminum alloy grades, the chemical composition of the alloy must be detected; the detection of chemical composition is the only way to distinguish aluminum alloy grades.
