Description
Aluminum 7075 Alloy Powder – <325 Mesh, 99.5+% Purity
Aluminum 7075 Alloy Powder is a high-strength aluminum alloy known for its exceptional mechanical properties and high strength-to-weight ratio. With zinc as the primary alloying element, this material offers superior fatigue resistance and is widely used in aerospace, defense, and high-performance engineering applications. The powder form (<325 mesh) enables high precision and consistent performance in additive manufacturing and powder metallurgy.
Although less corrosion-resistant and weldable than some other aluminum alloys, 7075 aluminum provides unparalleled strength and toughness in structural components subjected to extreme stress.
