7075 aluminum tube 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. 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.
