About Aluminum

Compare over 20 aluminum alloys to find the right material for you—all with material certificates for traceability.

Highly Conductive 1100 Aluminum Sheets

At 99% pure, 1100 is among the most conductive, corrosion-resistant, and formable aluminum alloys. Since it’s so soft, it’s often shaped into terminal blocks, raceways, and other parts that don’t need to be hard or strong. For high-stress electrical parts such as bus bars, look to 6101 aluminum instead.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
