Hemaokang Steel (Shandong) Co., Ltd. is a trusted supplier of high-quality aluminum coils, serving global manufacturers since 2025. Our 1.2mm 3003 H24 Aluminum Coil with 1000mm width is engineered to meet rigorous manufacturing standards, offering consistent performance and excellent formability. Whether you need components for automotive parts, roofing, or general sheet metal fabrication, this coil delivers reliable strength and surface finish, backed by our ISO9001 certified quality management system.
The 3003 alloy is widely recognized for its moderate strength, excellent corrosion resistance, and good weldability. The H24 temper indicates a strain-hardened and partially annealed condition, providing a balanced combination of strength and ductility ideal for bending, stamping, and other forming operations. With a precise thickness of 1.2mm and a generous width of 1000mm, this coil is optimized for high-volume manufacturing processes that require uniform dimensions and minimal waste.
Key Features & Specifications
- Consistent Thickness Tolerance: ±0.05mm, ensuring uniform material for stamping and bending applications.
- Flat Surface & Edge Quality: Free of scratches, oil stains, and burrs, suitable for visible end products.
- Excellent Formability: H24 temper allows tight bends without cracking, reducing scrap rates.
- Corrosion Resistance: Natural oxide layer protects against moisture and mild chemicals, extending product life.
- Weldability: Compatible with TIG, MIG, and resistance welding methods.
- Customizable Options: Available in various widths, coatings (e.g., PVDF, PE), and packaging upon request.
