1100 Aluminum Plate
1100 Aluminum Plate: Ultra-Pure Commercial Grade for Forming & Food Packaging
1100 aluminum plate (UNS A91100) offers 99.0%+ aluminum purity with exceptional workability, achieving 28-40% elongation in annealed conditions. Compliant with ASTM B209 and EN 485 standards, this non-heat-treatable alloy combines 90-145 MPa tensile strength with 98% IACS conductivity. Featuring ≤0.95% Si+Fe impurities, it excels in food-grade applications while maintaining ≤0.02mm/year corrosion rates in pH 6-8 environments. Available in 0.1-120mm thickness (±0.03mm tolerance) with H18/O tempers.
