Description of 3003 Aluminum Sheet
3003 aluminum sheet is one of the most commonly used non-heat-treatable aluminum alloys. It belongs to the 3000 series, featuring good corrosion resistance, excellent weldability, and high plasticity in the annealed condition. This alloy is often used in both decorative and structural applications where strength is less critical than corrosion resistance.
Gengfei offers wide-format, smooth-surfaced 3003 sheets and coils with excellent dimensional tolerance, cut-to-length service, and customizable surface treatments.
