7075 Aluminum Alloy
7075 aluminum alloy is a high-performance material known for its exceptional strength-to-weight ratio. As part of the 7000 series, it ranks among the strongest aluminum alloys available — offering tensile properties comparable to certain grades of steel. With zinc as its primary alloying element, this material is designed to withstand high stress and is a go-to choice for demanding applications across aerospace, automotive, and sporting goods.
Its composition balances strength, durability, and corrosion resistance, making it ideal for structural parts exposed to mechanical loads. Whether it’s reinforcing electric vehicles or taking flight in aerospace, 7075 is built to perform.
