5052 Aluminum Plate
5052 Aluminum Plate: High-Strength Al-Mg Alloy for Marine & Aerospace Applications
5052 aluminum plate (UNS A95052) is a non-heat-treatable Al-Mg alloy containing 2.2-2.8% magnesium and 0.15-0.35% chromium, delivering exceptional corrosion resistance in chloride environments. Compliant with ASTM B209 and AMS 4025 standards, this H32-temper alloy achieves 193-228 MPa yield strength with 12-20% elongation, making it ideal for marine components and aircraft fuel tanks requiring 138 W/m·K thermal conductivity. Featuring ≤0.40% Fe impurities and 70 GPa elastic modulus, it outperforms 3003 alloy by 35% in saltwater durability tests while maintaining 0.0495 μΩ·m electrical resistivity.
