7075 is a cold-treated forging alloy with high strength and far better than mild steel. 7075 is one of the most powerful alloys for commercial use. Common corrosion resistance, good mechanical properties and anode reaction. The fine grain size makes the deep drilling performance better, the tool wear resistance is enhanced, and the thread rolling is more different from the weight.

Physical properties and mechanical properties of
7075 aluminum tube:
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 lower. It is suitable to use the bearing structure at normal temperature and below 120 °C. The alloy is easy to process, has good corrosion resistance and high toughness. The
7075 aluminum tube is widely used in the aerospace and aerospace industries and is one of the most important structural materials in this field.
Tensile strength: 524Mpa
0.2% yield strength 455Mpa
Elongation: 11%
Modulus of elasticity: E/Gpa: 71.
