Welcome to Hemaokang Steel (Shandong) Co., Ltd. – your reliable partner in premium aluminum products. Our 3003 Aluminum Alloy Coil for Heat Exchanger is engineered to deliver outstanding thermal performance and corrosion resistance in demanding HVAC and refrigeration applications. With a thickness range of 0.3 to 4mm and H14 temper, this coil offers excellent formability and strength balance, making it ideal for fin, tube, and plate heat exchangers. Backed by our ISO9001-certified quality management system, each coil is produced to strict industry standards, ensuring consistent dimensions and surface quality.
Our 3003 aluminum alloy is specifically chosen for heat exchangers due to its high thermal conductivity (approximately 190 W/m·K), good weldability, and resistance to atmospheric and chemical corrosion. The H14 temper provides a work-hardened state that increases tensile strength while maintaining enough ductility for bending and stamping operations. Whether you need coils for evaporator fins, condenser coils, or custom heat transfer components, this product meets the technical requirements of modern thermal systems.

Advantages for Your Heat Exchanger Production
- Superior Thermal Performance: The 3003 alloy combined with H14 temper ensures high heat transfer efficiency, reducing energy consumption in your systems.
- Excellent Formability: Even at H14 temper, the material retains sufficient ductility for stamping, punching, and bending without cracking – ideal for complex fin geometries.
- Corrosion Resistance: Manganese alloying provides good resistance to moisture, chemicals, and atmospheric corrosion, extending the service life of heat exchangers.
- Consistent Quality: Our ISO9001-certified production process guarantees tight thickness tolerances, uniform surface finish, and reliable mechanical properties coil after coil.
- Customizable Dimensions: We offer coil width, inner diameter, and packaging tailored to your specific coil handling equipment and production line.
- Cost-Effective: 3003 alloy is more economical than higher-alloy alternatives while delivering performance suitable for most commercial and industrial heat exchangers.
- Global Supply Capability: With annual export value exceeding US$50 million, we ensure timely delivery to markets worldwide, including North America, Europe, Asia, and Africa.
