The hardness of the O-state 7075 aluminum alloy is very low, only about HB60, which is generally used for plates with a thickness of about 1MM. Because the state of 7075 aluminum alloy is different, that is, the process treatment when leaving the factory is different, the hardness of the national standard 7075 aluminum plate is also different.
At the same time, the hardness corresponds to the change in the material properties of 7075, and the hardness of 7075 aluminum plate and aluminum rod or aluminum profile is also different. The processing method can be implemented according to GB2006/3880. Common states are T6, T651, T7, T7651, T751, T73, O shape, etc. Customers can choose the appropriate 7075 aluminum material according to the use of the material.
