The hardness of aluminum sheets may differ based on the particular alloy and temper it has undergone processing to. Aluminum alloys are usually evaluated using the Rockwell hardness scale or the Brinell hardness scale. Typically, pure aluminum exhibits a low hardness rating, approximately 20-30 on the Rockwell B scale, whereas certain aluminum alloys can achieve a hardness level of up to 70 on the Rockwell C scale. However, it is essential to recognize that the hardness of aluminum can be further adjusted through different heat treatment methods, like annealing or tempering, which can have a significant effect on its ultimate hardness.
