1 the basic introduction of 6061 aluminium plate
The difference between the 6061 aluminum plate state T6 and T651 is in general, the internal stress of T6 will be relatively large, machining deformation, the most suitable processing condition should be T651, he is drawn on the basis of T6, the main alloying elements to eliminate internal stress 6061 Aluminum Alloy is magnesium and silicon, and the formation of Mg2Si phase. If a certain amount of manganese and chromium, can neutralize the bad effect of iron; sometimes add a small amount of copper or zinc, to improve the strength of the alloy, and the corrosion resistance decreased ficantly; there is a small amount of copper conductive materials, titanium and iron to offset the adverse effects on the conductivity of the zirconium; or titanium recrystallization grain refinement and control; in order to improve the cutting performance, adding lead and bismuth. In Mg2Si solid solution in aluminum, the alloy has artificial aging hardening function. The main alloy elements in 6061 aluminum alloy are magnesium and silicon, with medium strength, good corrosion resistance and weldability, and the oxidation effect is better.
Alcoa 6061 has excellent processing properties, good corrosion resistance, high toughness and processing after deformation, color film is easy, excellent oxidation effect and excellent characteristics.
Al-Mg-Si alloy, medium strength, with good plasticity and excellent corrosion resistance. Especially without stress corrosion cracking, its weldability, corrosion resistance and cold processing are good. It is a promising alloy with a wide range of use. It can be anodized and painted, and enamel can be painted to be used as a building decoration material. It contains a small amount of Cu, so the strength is higher than 6063, but quenching sensitivity is also higher than 6063. After extrusion, it can not achieve wind quenching. It needs re solution treatment and quenching aging to get higher strength.
2 what is the 6061 aluminum plate use for?
All kinds of industrial structures with high strength, weldability and corrosion resistance are required.
