Aluminum 7475 is an aircraft-grade heat-treatable alloy derived from 7075 aluminum, providing high strength, fracture toughness, and fatigue crack resistance. Its strength values are around 40% greater than alloy 7075 in the same tempers. Aluminum 7475 sheet/plate is commonly used for critical structural components like aircraft fuselage skins, bulkheads, wing parts, and armored vehicle components that require exceptional mechanical properties and resistance to crack propagation under high stress.
