The common states of 6061 aluminum plates include O state, T4 state, T6 state and T651 state. The T651 state alloy is formed by stretching based on the T6 state and eliminating internal stress, making it more suitable for processing and forming.
The difference between the two states of 6061 aluminum plate T6 and T651:
The difference between T6 and T651 is that under normal circumstances, the internal stress of T6 will be relatively large and it will be deformed during processing. The most suitable state for processing should be T651.
6061-T6 state: Cooled after solid solution heat treatment to achieve high strength, no cold working is performed;
6061-T651 status: Cooled after solid solution heat treatment to achieve high strength, and then cold stretched by a stretching machine to eliminate residual internal stress after heat treatment, so that it will not deform after deep processing to ensure the precision of machined products.
Since 6061-T651 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, it has many properties of magnesium and silicon alloys, good processing performance and excellent welding characteristics. And electroplating properties, good corrosion resistance, high toughness and no deformation after processing, the material is dense and defect-free and easy to polish, easy to apply color film, good oxidation effect and other excellent features.
The representative uses of 6061-T651 include aerospace fixtures, electrical fixtures, and communications fields. It is also widely used in automated mechanical parts, precision machining, mold manufacturing, electronic and precision instruments, SMT, PC board soldering carriers, etc.
