The Difference Between 6061 Aluminum Alloy T6 and T651

The main alloying elements in 6061 aluminum alloy are magnesium and silicon, which have medium strength, good corrosion resistance, weldability, and good oxidation effect. It is widely used in various industrial structural parts that require a certain strength and high antibacterial corrosion resistance.

6061 aluminum alloy is an Al-Mg-Si alloy with medium strength, good plasticity and excellent corrosion resistance. In particular, it has no tendency to stress corrosion cracking, and has excellent weldability, corrosion resistance and cold workability. It is a promising alloy with a wide range of applications. It can be anodized and colored, or painted with enamel, which is suitable for building decoration materials. It contains a small amount of Cu, so the strength is higher than that of 6063, but the quenching sensitivity is also higher than that of 6063. After extrusion, air quenching cannot be achieved. It needs to be re-solution treated and quenched and aged to obtain higher strength.

6061 aluminum alloy is used in various industrial structural parts that require certain strength, weldability and high corrosion resistance, such as the manufacture of trucks, building structures, ships, trams, furniture, mechanical parts, precision machining, and a wide range of industrial materials Wait.

The difference between the state of 6061 aluminum plate T6 and T651 is that in general, the internal stress of T6 will be relatively large, and the processing will be deformed. The most suitable state for processing should be T651, which is stretched on the basis of T6 to eliminate internal stress 6061 The main alloying elements of aluminum alloys are magnesium and silicon, which 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 conductive material. copper 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. In Mg2Si solid solution in aluminum, The alloy has artificial aging hardening function. The main alloying elements in 6061 aluminum alloy are magnesium and silicon, which have medium strength, good corrosion resistance, weldability, and good oxidation effect.

6061t6 is a commonly used state of aluminum alloy. Generally, it is in 6061t6 state unless otherwise specified, while 6061t651 is the best feature of 6 series aluminum alloys. It is a fighter in 6000 series aluminum alloys. It has excellent processing performance, Excellent welding characteristics and electroplating, good corrosion resistance, high toughness and no deformation after processing, dense material without defects and easy to polish, easy to color film, excellent oxidation effect and other excellent characteristics.

6061-T651 is the main alloy of 6061 aluminum alloy. It is a high-quality aluminum alloy product produced by heat treatment and pre-stretching process. Although its strength cannot be compared with 2XXX series or 7XXX series, its magnesium and silicon alloys have many characteristics. 6061- Representative applications of T651 include aerospace fixtures, electrical fixtures, and communications. It is also widely used in automated mechanical parts, precision machining, mold manufacturing, electronics and precision instruments, SMT, and PC board solder carriers.
