The difference between the state of 6061 aluminum tube T6 and T651 is that under normal circumstances, the internal stress of 6061 T6 will be relatively large, and the processing will be deformed. The most suitable state for processing should be 6061 T651. It is stretched on the basis of T6 to eliminate Internal stress, the main alloying elements of 6061 T651 round aluminum tube are magnesium and silicon, and form 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 increase the strength of the alloy without significantly reducing its corrosion resistance; there is a small amount of conductive materials To offset the adverse effects of titanium and iron on electrical conductivity; zirconium or titanium can refine grains and control recrystallization; in order to improve machinability, lead and bismuth can be added. Mg2Si is solid-dissolved in aluminum, which makes the alloy have artificial age hardening function. The main alloying elements in 6061 T651 round aluminum tube are magnesium and silicon, which have medium strength, good corrosion resistance, weldability and good oxidation effect.

6061 T651 round aluminum tube has excellent processing performance, good corrosion resistance, high toughness, no deformation after processing, easy color film, and excellent oxidation effect.

It belongs to Al-Mg-Si series alloy, with medium strength, good plasticity and excellent corrosion resistance. In particular, it has no stress corrosion cracking tendency, its weldability is excellent, corrosion resistance and cold workability are good, and it is a very promising alloy with a wide range of applications. It can be anodized and colored, or painted with enamel, suitable for building decoration materials. It contains a small amount of Cu, so the strength is higher than 6063, but the quenching sensitivity is also higher than 6063. Air quenching cannot be achieved after extrusion, and re-solution treatment and quenching aging are required to obtain higher strength.
