3003 H14 Aluminum Coil – General Corrosion Resistant Grade
Product Overview
3003 aluminum coil is the most widely used Al-Mn rust-proof aluminum product in the industry. As a classic 3-series aluminum alloy, it delivers excellent corrosion resistance, moderate strength and outstanding formability at a cost-effective price point. This H14 half-hard grade is our standard specification, optimized for pipeline insulation jacketing, architectural cladding, light fabrication and general industrial applications. It can be easily bent, roll-formed, stamped and welded into various shapes and profiles.
