7075 Aluminum plate
7075 Aluminum Plate: Ultra-High-Strength Aerospace Alloy for Critical Structural Applications
7075 aluminum plate (UNS A97075) is a heat-treatable zinc-magnesium-copper alloy containing 5.1-6.1% Zn and 1.2-2.0% Cu, delivering exceptional 572 MPa tensile strength with superior fatigue resistance. Certified to AMS 4048 and ASTM B209 standards, this T651-temper alloy achieves 11% elongation and 175 HV hardness, making it the premier choice for aerospace components and defense systems requiring strength-to-weight ratios exceeding 280 kN·m/kg. Available in 0.1-120mm thickness (±0.05mm tolerance) with 130 W/m·K thermal conductivity for high-stress thermal management applications.
