6061 T6 aluminum alloy sheet
6061 t6 aluminum alloy plate has three different common heat treatment states: O, T4 and t6. The difference between the state of 6061 o aluminum sheet T6 and T651 is that in general, the internal stress of T6 will be relatively large, and the processing will be deformed. 6061 T651 should be a more suitable processing state, which is stretched on the basis of the T6 state to eliminate internal stress. The hardness of 6061 aluminum alloy plate has a lot to do with its composition.
