3003 Aluminum Plate
3003 Aluminum Plate: High-Strength Manganese Alloy for Structural & Heat Exchange Systems
3003 aluminum plate (UNS A93003) is an Al-Mn alloy offering 20-40% higher strength than 1000-series grades, with 110-285 MPa tensile strength range and exceptional workability. Compliant with ASTM B209/AMS 4003 standards, this H14-temper alloy combines 1.0-1.5% manganese content with ≤0.12% Cu impurities for superior corrosion resistance (≤0.015mm/year in pH 5-9 environments). Ideal for roofing, heat exchangers, and food processing equipment requiring 190 W/m·K thermal conductivity and 23.1×10⁻⁶/°C thermal expansion stability.
