What is the strongest aluminum alloy available?

The strongest aluminum alloy available is typically considered to be 7075. It is an aerospace-grade alloy known for its high strength and excellent mechanical properties. The main elements in 7075 aluminum are aluminum, zinc, and small amounts of copper, magnesium, and chromium.

7075 aluminum has an ultimate tensile strength of 570-640 MPa and a yield strength of 480-550 MPa. It also exhibits good fatigue resistance and high corrosion resistance.

Due to its exceptional strength-to-weight ratio, 7075 aluminum is commonly used in applications that require high strength and durability, such as aerospace components, military equipment, and high-performance sporting goods.
