ALUMINIUM PLATES – ALLOY 7075 T651
Properties of Aluminium Alloy 7075
Aluminium alloy 7075 is one of the strongest aluminum alloys available, it can match the strength of many steels while giving a considerable weight saving advantage. 7075 is produced from mixing Aluminium with Zinc, Magnesium and Copper, this alloy is tough workable and light. It also has excellent properties at low temperatures.
Applications of Aluminium Alloy 7075
Due to its strength this alloy is often used in molds for tools, bike frames and other sports equipment. Alloy 7075 is also commonly used in the automotive, aerospace and defense applications and high-risk applications (military, skyscrapers). The fatigue strength of the alloy is also important for repetitive loadings, such as in aviation or motor vehicles.
