Introduction of 7055 Aviation Grade Aluminum Alloy Forgings
7055 Aviation Grade Aluminum Alloy Forgings have extremely high strength, good toughness and good stress corrosion resistance.
In the 1980s, the United States and others successfully developed 7055 Aviation Grade Aluminum Alloy Forgings on the basis of 7150. The strength is about 10% higher than that of 7150 and has high comprehensive performance. It is used for the upper wing skin and wing stringer of Boeing 777 passenger aircraft. .
