6061 T6 Aluminum Properties

2022-05-07

6061 aluminum alloy belongs to the AL-Mg-Si series, which is characterized by medium strength, good plasticity, excellent weldability and corrosion resistance. The content of Mg and Si in the 6061 aluminum alloy is slightly higher than that of 6063 aluminum alloy, and contains a small amount of copper, so the strength is higher than that of 6063 aluminum alloy, and the quenching sensitivity is also higher than that of 6063 aluminum alloy. Now 6061-T6 aluminum alloy has been widely used in the industrial production of large aluminum alloy profiles with complex cross-section. In order to obtain higher mechanical 6061 t6 aluminum properties, the alloy must be rapidly quenched after solid solution to obtain higher supersaturation and solid solution.

 
The main alloying elements of 6061 aluminum alloy are magnesium and silicon and form the Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the bad effects of iron? Sometimes a small amount of copper or zinc is added to improve the strength of the alloy. Without significantly reducing its corrosion resistance, there is also a small amount of copper in the conductive material. To offset the adverse effects of titanium and iron on electrical conductivity, zirconium or titanium can refine grains and control recrystallization structure. In order to improve machinability, lead and bismuth can be added. The main strengthener Mg2Si is solid-dissolved in aluminum to make the alloy have artificial age hardening function. Therefore, in order to have better mechanical properties, qualified chemical composition is the premise, especially for the formation of the main strengthening phase Mg2Si, it is necessary to ensure that the chemical composition meets the requirements of the national standard, so that good mechanical 6061 t6 aluminum properties can be obtained after post-processing.
 
The production process of 6061 aluminum sheet is prepared from a semi-solid slurry to form a billet with a certain alloying element content. After hot rolling and cold rolling, the edges and corners are cut and the surface is clear to form a 6061 aluminum sheet with a specific length and width. Through strict quality control in the production process, the microstructure and 6061 t6 aluminum properties castings have been developed to the greatest extent. In terms of mold manufacturing in the later stage, the required preheating temperature is 400-425 degrees, and the produced products have dense structure and fine grains, which are much better than ordinary steel plates in terms of tensile properties and processing properties.
