Sheet & Plate



While most aluminum sheet and plate producers simply supply materials, Alcoa Global Flat Rolled Products provides unmatched research and development capabilities.

We specialize in creating customized alloys that meet the unique demands of each application. Through structural design studies, we help our customers understand and predict the performance of different material options.

While Alcoa has long produced alloy 5083 for the defense industry,we also offer many innovative new alloys. For instance, we recently introduced CR56 and 7085 armor plate. CR56 allows original equipment manufacturers to use traditional welding techniques during assembly without compromising long-term vehicle performance. For appliqué armor, 7085 delivers improved ballistic and strength performance while reducing stress corrosion cracking.
