6061-T651 is the main alloy of 6061 alloys. It is a high-quality aluminum alloy product produced by heat treatment and pre-drawing process. Although its strength cannot be compared with the 2XXX series or 7XXX series, it has many magnesium and silicon alloy characteristics, such as excellent machining performance, excellent welding characteristics, electroplating, good corrosion resistance, high toughness, no deformation after processing, material density without defects, easy polishing, easy coloring film, excellent oxidation effect, etc

The difference between T6 and T651 is that, in general, T6 has greater internal stress and will deform during machining. The most suitable state for machining should be T651, which is stretched on the basis of T6 to eliminate internal stress
6061-T6 state: cooling after solution heat treatment to achieve high strength no longer cold working
6061-T6511 status: Solution heat treatment after cooling to achieve high strength, then correction straightening process
6061-T651 state: cooling after solution heat treatment to reach high strength, and then cold drawing by drawing machine to eliminate residual internal stress after heat treatment, to ensure the accuracy of machined products, no deformation after further processing.
