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. 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 state suitable for processing should be T651, which is stretched on the basis of T6 to eliminate internal stress.

6061-T6 Status:Cooling after solution heat treatment to achieve high strength, no cold working.

6061-T651 Status:After solution heat treatment, it is cooled to achieve high strength, and then cold stretched by a stretching machine to eliminate the residual internal stress after heat treatment, so that it will not deform after deep processing to ensure the precision of machined products.

The main alloying elements of 6061 aluminum alloy are magnesium and silicon, and form Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the bad effect of iron; sometimes a small amount of copper or zinc is added to improve the strength of the alloy, while It does not significantly reduce its corrosion resistance; there is a small amount of copper in the conductive material to offset the adverse effects of titanium and iron on conductivity; zirconium or titanium can refine grains and control recrystallization; For cutting performance, lead and bismuth can be added. Mg2Si is dissolved in aluminum, which makes the alloy have artificial age hardening function. The main alloying elements in 6061 aluminum alloy are magnesium and silicon, which have medium strength, good corrosion resistance, and weldability. , and the oxidation effect is better.

6061-T6 is a commonly used aluminum alloy state. Generally, unless otherwise specified, it is generally 6061-T6 state, while 6061-T651 is the best characteristic of 6 series aluminum alloys and 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- The representative applications of T651 include aerospace fixtures, electrical fixtures, communications, and are also widely used in automated mechanical parts, precision machining, mold manufacturing, electronics and precision instruments, SMT, PC board solder carriers, etc.
