Product Description
7075 aluminum bar is a cold-treated forged alloy with high strength, far superior to mild steel. 7075 is one of the strongest alloys commercially available. Normal corrosion resistance, good mechanical properties and anodic reaction. The finer grains provide better deep drilling performance, enhanced tool wear resistance and differentiated thread rolling. 7075 aluminum is called ultra-high-strength aluminum alloy. The yield strength of the alloy is close to the tensile strength, the yield ratio is high, and the specific strength is also high, but the plasticity and high temperature strength are low. The alloy is easy to process, has good corrosion resistance and high toughness. This alloy is widely used in aviation and aerospace and has become one of the most important structural materials in this field. 7075 aluminum bar products have the characteristics of high-strength heat-treatable alloying, good mechanical properties, workability, ease of processing, wear resistance, corrosion resistance, oxidation resistance and so on.
