This specification covers 55% aluminum-zinc alloy-coated steel sheets in coils and cut lengths for applications requiring corrosion resistance or heat resistance or both. The material is available in several designations:commercial steel, forming steel, drawing steel, high temperature steel, and structural steel.
Chemical Composition and Properties of Aluminum Alloys Aluminum has high reflectivity and can be used for decorative applications. Some aluminum alloys can match or even exceed the strength of common construction steel. Aluminum retains its toughness at very low temperatures, without becoming brittle like carbon steels. Aluminum
