3003 H24 Aluminium Coil
The 3003 H24 Aluminium Coil is a widely utilized material known for its excellent corrosion resistance, moderate strength, and outstanding workability. Popular in diverse sectors, this aluminum alloy balances affordability with performance, making it an ideal choice for architectural, industrial, and commercial applications.
3003 aluminium alloy belongs to the 3xxx series, primarily alloyed with manganese to enhance its strength relative to pure aluminum. The H24 temper indicates a strain-hardened and partially annealed state, where the material provides a good combination of strength and formability.
Features
- Corrosion Resistance: Outstanding resistance in a wide range of environments, including marine atmospheres.
- Workability: Easily wrought into various shapes and forms, ideal for rolling, bending, and forming.
- Strength: Higher than 1100 aluminium but still moderate, adequate for many structural purposes.
- Surface Finish: Good shiny finish preferable for decorative and functional surface treatments.
