What's the hardness of 7075 aluminum bars?
Hardness of 7075 aluminium bars: HB 60.7075 is a cold forging alloy, high strength, far better than mild. 7075 is one of the most powerful alloys commercially available. General corrosion resistance, good mechanical properties and anodic reaction. The fine grain makes the deep drilling performance better, the tool wear resistance is enhanced, and the thread rolling system is different from the heavy rolling.
