ã€ALUMINIUM NETWORK】2A12 and 6061 are heat-treatable aluminum alloys, which are indistinguishable from each other after heat treatment. Because the price difference between the two is huge, the difference is probably more than 10,000 yuan/ton, so many dealers use it in the market. 6061 to impersonate 2A12 sales, how can identify the two is a problem for the user? First, the hardness: 6061 hardness after heat treatment at 90HB, and 2A12 can reach 120HB near the difference in hardness between the two, if you measure the brightness of the device, you can measure the hardness. Second, the density: If you do not have a hardness tester, then there is a simple way, the density difference between the two, 6061 density can only reach 2.7, and 2A12 due to high copper alloy content, density can reach 2.78-2.79 near the Calculate the product density according to the aluminum weight calculation formula. Weight Formula: Thickness (mm) * Density (2.7/2.78) * Length (m) * Width (m) = Weight Look at the weight of the final product, which can be distinguished Third, if there are doubts, it can be detected by a third party, and the content of each alloying element can be analyzed by an elemental analysis instrument. Then it can be determined against the national standard alloy content.
