7075 is a cold-treated forged alloy with high strength, far superior to mild steel. 7075 is one of the strongest commercial alloys. Ordinary corrosion resistance, good mechanical properties and anodic reaction. Fine grains make deep drilling performance better, tool wear resistance enhanced, and thread rolling more unique.
7075 aluminum is known as an ultra-high strength aluminum alloy. The yield strength of this alloy is close to tensile strength, the yield strength ratio is high, and the specific strength is also high, but the plasticity and high temperature strength are low. It is suitable for load-bearing structural parts used at room temperature and below 120°C. The alloy is easy to process, has good corrosion resistance and high toughness. The alloy is widely used in the aerospace field and has become one of the most important structural materials in this field.
