The 7075 aluminum round bars(rod) is a cold treatment of forging alloy, high strength, far better than mild steel. 7075 aluminum round bars(rod) is one of the most powerful commercial alloys. Common corrosion resistance, good mechanical properties and anodic reaction. Fine grain makes deep drilling performance better, tool wear resistance increased, thread rolling is more different from heavy weight.
