7075 aluminum alloy boasts exceptional strength, making it one of the strongest aluminum alloys in the world. Its tensile strength reaches 570 MPa (83,000 psi) and its yield strength is 500 MPa (73,000 psi).
These values indicate that 7075 aluminum alloy exhibits exceptional resistance to deformation and fracture under load. Compared to other aluminum alloys such as 6061 and 5052, 7075 aluminum alloy offers significantly higher strength, but lower corrosion resistance and weldability. It is typically used in applications requiring maximum strength.
