7075 Aluminum Plate
7075 is a cold treated forged alloy with high strength, far superior to soft steel. Ordinary corrosion resistance, good mechanical properties, and anodic reaction. Fine grains improve the performance of deep drilling, enhance tool wear resistance, and make thread rolling more unique.
