Aluminum sheet 6061 has excellent machinability, good corrosion resistance, high toughness, no deformation after processing, easy coloring film, excellent oxidation effect and other excellent characteristics. It belongs to Al-Mg-Si series alloy, with medium strength, good plasticity and excellent corrosion resistance. Among the aluminum sheet 6061 alloys, the aluminum alloy is 97.9%, the magnesium is 1%, the silicon is 0.6%, the copper is 0.28% and the chromium is 0.2%.
The main alloying elements of 6061 aluminum sheet are magnesium and silicon, mainly in the shape of aluminum sheet, the tempers generally are T6, T4 and T651. The hardness of 6061 aluminum sheet is more than 95, which is widely used in mechanical processing industry. A small amount of copper or zinc can be added in the production to improve the strength of the alloy without significantly reducing its corrosion resistance. There is also a small amount of copper to offset the negative effect of titanium and iron on conductivity. To improve the machinability of aluminum sheet 6061, lead and bismuth can be added. 6061 aluminum plate can be sued for process industrial structure with high strength, weldability and corrosion resistance requirements, such as manufacturing trucks, towers, ships, trams, furniture, mechanical parts, precision processing and other pipe, rods, profiles, sheets.
1, 6061 aluminum sheet has excellent processing performance, good corrosion resistance, high toughness and deformation after processing, easy coating, good oxidation effect and other excellent features, after annealing can still maintain a good operability. In particular, the tendency of non stress corrosion cracking, good weldability, good cold workability
2, Advanced equipment 3000T tensile machine, according to process requirements, 1.0%–3.0% on the plate within the stipulated time of permanent tensile plastic deformation, the elastic deformation to plastic deformation, to eliminate the residual stress after quenching, ensure product deformation in machining
3, In the process of customer cooperation Haomei aluminum summed up the customer’s specific requirements for the 6061 aluminum sheet :
(1) the required thickness tolerance is small (usually positive).
(2) hardness should be up to (above HB).
(3) the deformation after processing is small.
(4) smoothness is better.
