Aluminum Alloy 1100 McMaster-Carr
These sheets and bars are tempered to a 1/2-hard or full-hard state to make them over twice as strong as standard 1100 aluminum. Because 1100 aluminum is 99% pure it offers superior corrosion resistance and electrical conductivity. Temper H19 foil is often used as EMI/RFI shielding in electronic applications.
