3105 Aluminum Sheet Overview
3105 Aluminum Sheet is a non-heat-treatable aluminum-manganese alloy containing approximately 98% aluminum with controlled additions of manganese and magnesium to improve strength and corrosion resistance.
Compared with 1100 aluminum sheet and 3003 aluminum sheet, AA3105 offers higher strength while maintaining excellent formability and weldability. These characteristics make it one of the most widely used alloys for architectural panels, roofing sheets, insulation jacketing, rainwater systems, and painted aluminum products.
As an experienced aluminum sheet manufacturer, Xi'an Dongmeng Group supplies 3105 aluminum sheet in various tempers and dimensions for global distributors, EPC contractors, fabricators, and OEM manufacturers.
