7075 aluminum bar is close to the tensile strength, the yield ratio is high, the specific strength is also high, but the plasticity and high temperature strength are low, so it is suitable for use as a bearing structure at room temperature and below 120°C. Parts, alloys are easy to process, have good corrosion resistance and high toughness. The alloy is widely used in the aviation and aerospace fields and has become one of the most important structural materials in this field.
The main feature of 7075 aluminum bar is its high hardness. 7075 is a high-hardness and high-strength aluminum alloy, which is often used in the manufacture of aircraft structures and futures. It requires the manufacture of high-stress structural parts and molds with high strength and strong corrosion resistance.
7075 aluminum bar usually have such types in production: 7075 aluminum round bar, 7075 aluminum square bar, 7075 aluminum flat bar, 7075 aluminum hexagon bar and 7075 aluminum angle bar.
