3105 aluminum coil is a 3000-series aluminum-manganese alloy known for its excellent corrosion resistance, formability, weldability, and moderate strength. It consists mainly of aluminum with small additions of manganese, magnesium, and other elements to enhance mechanical properties without heat treatment. This alloy is widely used across industries including building envelopes, kitchen equipment, bottle caps, transportation, and industrial components where durable, lightweight, and easy-to-process metal is needed.

This alloy is widely used across industries including building envelopes, kitchen equipment, bottle caps, transportation, and industrial components where durable, lightweight, and easy-to-process metal is needed.
The alloy is available in multiple tempers (O, H12, H14, H16, H18, H24, H26, etc.), allowing customers to choose the right balance of strength and formability for their application. 3105 aluminum coils can also be surface-treated with mill, anodized, pre-painted (PE/PVDF), embossed, or coated finishes to meet specific design and environmental requirements.
Key applications include exterior building cladding, gutters and downspouts, decorative panels, lampshade materials, container and packaging components, and consumer appliance parts. The alloy’s versatility makes it ideal for both architectural and manufacturing markets.
