Hemaokang Steel (Shandong) Co., Ltd. proudly offers the ASTM B209 3003 Aluminum Coil in thicknesses from 0.5mm to 3.0mm, with a H14 temper and a clean mill finish. As a manufacturer dedicated to quality and reliability, we supply this versatile aluminum coil for general fabrication projects across industries that demand consistent performance, ease of forming, and excellent corrosion resistance. Our coil is produced to meet the rigorous requirements of ASTM B209, ensuring dimensional accuracy and metallurgical integrity for every batch.
This 3003 aluminum coil is a workhorse material for fabricators, sheet metal shops, and manufacturers. The H14 temper provides a balanced combination of strength and formability, making it suitable for stamping, bending, spinning, and welding operations. The mill finish offers a smooth, uncoated surface that is ideal for applications where the material will be painted, coated, or used as-is in interior and exterior components. With a thickness range starting at 0.5mm, this coil is equally suited for lightweight enclosures and heavy-duty structural panels.
Key Product Features
- Premium Alloy 3003 – The addition of manganese provides up to 20% greater strength than pure aluminum (1100 series) while maintaining excellent workability.
- H14 Temper – Strain-hardened to a half-hard state, offering a good balance between yield strength and ductility for common forming operations.
- ASTM B209 Compliance – Manufactured and tested to meet the internationally recognized standard for aluminum sheet and plate.
- Uniform Thickness Tolerance – Precision-rolled for consistent thickness across the entire coil width, reducing waste and ensuring predictable forming results.
- Mill Finish Surface – A clean, bright, and uniform surface that is ready for immediate fabrication or subsequent finishing processes like anodizing or painting.
- Wide Width Range – Available in various widths to suit your specific fabrication needs; custom slitting options available upon request.
- Excellent Corrosion Resistance – Naturally resistant to atmospheric corrosion, making it suitable for outdoor and marine environments.
- Excellent Weldability – Easily welded using standard techniques, with no special pre- or post-weld treatment required for most applications.
- Lightweight and Durable – One-third the weight of steel while providing reliable mechanical performance for structural and non-structural uses.
- Eco-Friendly and Recyclable – Aluminum is infinitely recyclable without loss of quality, supporting sustainable manufacturing practices.

Applications and Benefits
Our 3003 aluminum coil is engineered for general fabrication, meaning it adapts to a wide range of manufacturing processes and end-uses. Common applications include:
- Sheet metal fabrication – ductwork, enclosures, panels, brackets, and housings.
- Roofing and siding – standing seam panels, corrugated sheets, and trim components.
- Automotive components – heat shields, trim, fuel tanks, and structural reinforcements.
- Heat exchangers – fins, tubes, and condenser coils due to its good thermal conductivity.
- Cooking utensils and food processing equipment – safe, non-toxic, and easy to clean.
- General industrial equipment – guards, covers, chutes, and hoppers.
For fabricators, the benefits of choosing this coil include reduced tool wear due to consistent hardness, minimal surface defects that could compromise cosmetics, and excellent flatness that helps achieve precise cuts and bends. The H14 temper also retains sufficient ductility for moderate forming operations without spring-back issues, improving productivity and reducing scrap.
