 First, the 6061 basic introduction 
 6061 aluminum state T6 and T651 of the difference is that under normal circumstances, the T6, the internal stress is relatively large, the processing will be deformed, the most suitable processing status should be T651, he is in the T6 stretch, eliminate internal stress 6061 aluminum alloy elements are magnesium and silicon, and the formation of Mg2Si phase. If a certain amount of manganese and chromium, can neutralize the bad effect of the iron; sometimes add a small amount of copper or zinc, to improve the strength of the alloy, without its corrosion resistance decreased significantly; a small amount of conductive material copper, in order to offset the adverse effects of the electrical conductivity of titanium and iron; zirconium or titanium grain refinement and control of the recrystallized microstructure; to improve may be cutting performance can be added to the lead and bismuth. Mg2Si solid solution in aluminum alloy to artificial aging hardening function. The major alloying elements for magnesium and silicon in the 6061 aluminum alloy, with a medium strength, good corrosion resistance, weldability, oxidation is better. 
 Alcoa 6061 has excellent processing properties and good corrosion resistance, high toughness and processing after deformation, color film is easily oxidized with excellent results and other fine features. 
 The case of Al-Mg-Si alloy of medium strength, good ductility and excellent corrosion resistance. In particular, no stress corrosion cracking tendency, welding quality, and good corrosion resistance and cold, is a way to use a wide range of promising alloys. Anodizing can also be painted enamel, to adapt for the building and furnishing materials. Containing a small amount of Cu, and thus the intensity is higher than 6063, but the quenching sensitivity is higher than 6063, the wind quenching can not be achieved after extrusion, the need to re-solution treatment and quench aging in order to obtain a higher strength. 
 Edit this paragraph typical use 
 Requires a certain strength, weldability and corrosion resistance of high industrial structure, 
 Such as the manufacture of trucks, ride-style buildings, ships, trams, furniture, machine parts, precision processing.
