7075 aluminum rod

Brand: Alcoa Caesars 　　 Standard: ASTM AMS QQ

7075 is a cold-treated forging alloy with high strength, far better than mild steel. 7075 is one of the most powerful alloys commercially available. General corrosion resistance, good mechanical properties and anode reaction. The small grains make the deep drilling performance better, the tool wear resistance is enhanced, and the thread rolling is more different.

Tensile strength 524Mpa 0.2% Yield strength 455Mpa elongation 11%

Hardness 150HB

The material composition and process are strictly controlled to ensure that the material composition and mechanical properties of each batch meet or exceed the national standard.

7075 aluminum rod processing characteristics

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. Parts, alloys are easy to process, have good corrosion resistance and high toughness. The alloy is widely used in aviation and aerospace fields, and has become one of the most important structural materials in this field.
