This alloy was originally developed in 1936 by the Sumitomo Metal Industries in Japan, which has since merged with Nippon Steel. Japan was in a full-scale wartime mode then and had begun working to develop a lightweight, high strength-to-density ratio aluminum alloy that could be used in build faster and stronger aircraft for its Imperial Navy.
The development of 7075 aluminum was done in secret, and it wasn’t until 1940 that it was used in the production of planes, specifically the Mitsubishi A6M Zero. The Mitsubishi Zero was considered to be the best carrier-based fighter of the time.
This alloy was first used in the United States and other countries in 1943 and also used extensively by the aircraft industry almost immediately. Because of its high strength-to-weight ratio, 7075 was a natural choice for the new generation of aircraft being produced by the Allies in WWII.
Applications of 7075 Aluminum Alloy
7075 is widely used in aerospace, marine and transportation industries. This is because high strength and light weight properties are critical there. In addition to aircraft parts and components. 7075 can be found in high-end bicycles, molding materials for the plastics and tool industries, and even military applications. All of these products and components require the improved thermal properties that the 7075 alloy provides.
