What is the difference between the 6061-T6 aluminum pipe and the common aluminum pipe?
The T6 state is after the heat treatment of aluminum (solution treatment after artificial aging state), sold on the market are generally after heat treatment of aluminum, some without considering the cost of materials and heat treatment processing and sale, in terms of hardness to lower than T6
Alcoa 6061-T651 has excellent processing properties, corrosion resistance, high toughness and processing after deformation, color film is easy, excellent oxidation effect and excellent characteristics of good.Al-Mg-Si series alloy, medium strength, with good plasticity and excellent corrosion resistance. Especially the tendency of non stress corrosion cracking, which has good weldability, good corrosion resistance and cold workability, is a widely used and promising alloy. It can be anodized, painted, or painted with enamel. It is suitable for building decoration materials. It contains a small amount of Cu, so the strength is higher than 6063, but the sensitivity of quenching is higher than that of 6063. After extrusion, the air can not be quenched, and it needs to be solved again by solid solution treatment and quenching aging so as to obtain higher strength.
The difference between the 6061 aluminum 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, eliminate the internal stress and the main alloy element 606 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 significantly; 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 can refine the grain and control of recrystallization; in order to improve the cutting performance, adding lead and bismuth. In Mg2Si solution in aluminum, the alloy has artificial aging hardening function. The main alloy elements in 6061 aluminum alloy are magnesium and silicon, which have moderate strength, good corrosion resistance, weldability and good oxidation effect.
