1100 Aluminum Coil 99% Pure Alloy with 75-165 MPa Tensile Strength for Storage Tanks and Electrical Components

1100 aluminum coil is a commercially pure aluminum alloy (≥99.0% aluminum content) offering excellent corrosion resistance, high thermal and electrical conductivity, and superior workability. This alloy is widely used for general-purpose applications across multiple industries.

With a minimum 99% aluminum composition, 1100 aluminum is considered commercially pure. The remaining 1% typically consists of trace elements including iron and silicon.

• High ductility for easy forming, bending, and drawing operations
• Excellent weldability compatible with TIG, MIG, and resistance welding
• Good machinability (requires proper tooling for optimal results)
• Non-magnetic properties with reflective surface characteristics

• Lower strength limits suitability for high-stress applications
• Not heat-treatable - strengthening achieved only through cold working
• Limited wear resistance compared to other aluminum alloys

• Food & Chemical Industry: Storage tanks, packaging foils, and cans
• Electrical Components: Busbars, conductors, and heat sinks
• Decorative & Architectural: Trim components, nameplates, and signage
• General Fabrication: Sheet metal work, spun hollowware, and rivets
