Welcome to Hemaokang Steel (Shandong) Co., Ltd. – your reliable partner for premium aluminum coil solutions. Since our establishment in 2025, we have rapidly grown into an enterprise with an annual export value of US$50 million – US$100 million, serving clients across North America, South America, Europe, Asia, Africa, and Oceania. Our 3003 H24 Aluminum Coil is designed to meet the highest industry standards, backed by a 1-year warranty and full technical support. Every coil comes with a Mill Test Certificate to guarantee traceability and quality.
Product Overview
The 3003 alloy is a non-heat-treatable aluminum-manganese alloy, known for its excellent corrosion resistance, good formability, and moderate strength. The H24 temper indicates a strain-hardened and partly annealed condition, providing a balanced combination of strength and ductility. This makes our aluminum coil ideal for applications requiring both rigidity and the ability to be shaped or drawn.
Key Features & Benefits
- Superior Corrosion Resistance – 3003 alloy offers excellent resistance to atmospheric, chemical, and marine environments, extending the lifespan of your products.
- Excellent Workability – The H24 temper allows for easy bending, deep drawing, and forming without cracking or tearing, reducing production waste.
- Consistent Mechanical Properties – Strict process control ensures uniform tensile strength, yield strength, and elongation across the entire coil.
- Lightweight yet Durable – At approximately one-third the weight of steel, 3003 aluminum reduces transportation costs and structural load while maintaining adequate strength.
- Smooth Surface Finish – Our coils undergo advanced surface treatment to minimize scratches, oil stains, and other defects, ensuring a clean and attractive finish.
- Customizable Dimensions – Available in thicknesses from 0.2 mm to 6.0 mm and widths from 100 mm to 2000 mm, tailored to your specific needs.
- Comprehensive Quality Assurance – Each coil is tested in-house and accompanied by a Mill Test Certificate (MTC) confirming chemical composition, mechanical properties, and temper.
- Reliable Warranty – Enjoy peace of mind with a 1-year warranty covering manufacturing defects, plus dedicated technical support from our experienced team.
