The 7050 is a high strength heat treatable alloy. It has high strength, anti stripping corrosion and stress corrosion cracking resistance. It is commonly used in aircraft structural parts for medium plate extrusion, free forging and die forgings.

7075 aluminum is called super high strength aluminum alloy. The yield strength of the alloy is close to tensile strength, the yield ratio is high, and the specific strength is very high. But the strength of plastic and high temperature is lower than that of the alloy. 7075 aluminum tube pipe is suitable for the bearing structure parts under normal temperature and below 120 C. The alloy is easy to process, and has good corrosion resistance and high toughness. 7075 aluminum tube pipe is widely used in the field of aviation and aerospace and has become one of the most important structural materials in this field.
7178 aluminum tube pipe has the characteristics of high strength, which is used for manufacturing aerospace components with high compression yield strength.
