3003 H14 Aluminum Coil

Haomei Aluminum supplies 3003 H14 aluminum coil for roofing, insulation, HVAC components and general industrial fabrication. The 3003 alloy offers good corrosion resistance and formability, making it suitable for applications that require reliable forming performance and consistent material specifications.

• Thickness: 0.2–8 mm
• Width: 100–2650 mm
• Temper: H14 / H24
• Standard: ASTM / EN

20% Higher Strength

Approximately 20% stronger than 1100 series aluminum, offering improved durability for industrial applications.

H14 Half-Hard Temper

Provides a balance of strength and formability, allowing bending up to 90° without cracking.

Excellent Workability

Ideal for bending, stamping, and welding, ensuring efficient processing in manufacturing.

HVAC and Heat Exchanger Components

3003 H14 aluminum coil is suitable for various formed parts used in heating, ventilation, air conditioning, and refrigeration equipment. Its thermal conductivity and workability make it useful in equipment that combines heat transfer with lightweight construction.

• HVAC ductwork and ventilation panels
• Selected heat exchanger and cooling components
• Refrigeration equipment panels and covers
• Insulation jacketing for pipes and equipment

For fin stock and brazed heat exchangers, the required temper, thickness, surface condition, and joining process should be confirmed before specifying the material.

Building and Architectural Products

In architectural fabrication, 3003 H14 aluminum coil is used to produce formed and finished components where moderate strength, corrosion resistance, and consistent surface quality are important.

• Roofing panels and wall cladding
• Gutters, downspouts, and architectural trim
• Decorative building panels
• Aluminum composite panel facing stock, where specified

For exterior applications, coating compatibility, weather exposure, forming requirements, and surface appearance should be considered when selecting the coil.

Transportation and Equipment Fabrication

The combination of moderate strength and formability makes 3003 H14 aluminum coil a practical option for selected non-structural parts used in transportation equipment and industrial assemblies.

• Vehicle interior trim and formed panels
• Truck and trailer equipment panels
• Protective covers and equipment enclosures
• Brackets, guards, and general sheet metal parts

Alloy selection should reflect the component's load, vibration, forming requirements, and service environment. Structural or safety-critical parts require separate material qualification.

Battery Enclosures and Thermal Management

3003 aluminum is used in selected battery-related components and thermal management applications. H14 coil may be suitable when the required stiffness and forming characteristics match the component design.

• Selected battery enclosure and cover components
• Formed panels for energy storage equipment
• Thermal management component housings
• Heat dissipation parts designed for the specified alloy and temper

Deep-drawn battery shells and brazed liquid cooling plates may require a softer temper or a specially designed brazing sheet. Confirm the forming and joining process before choosing 3003 H14 coil.

Industrial Containers and Process Equipment

For suitable service conditions, 3003 H14 aluminum coil can be fabricated into non-pressure containers, equipment panels, and formed parts used in industrial environments.

• Non-pressure storage tank components
• Industrial trays, bins, and formed containers
• Equipment covers and protective panels
• Selected chemical process equipment components

Corrosion resistance depends on the stored material, chemical concentration, temperature, and operating conditions. Compatibility should be assessed for each application rather than assumed from the alloy designation alone.

Home Appliances and General Sheet Metal Parts

3003 H14 aluminum coil is also used in appliance manufacturing and general metalworking, particularly for parts that need to be lightweight, formable, and resistant to everyday environmental exposure.

• Refrigerator and freezer panels or liners
• Lighting fixtures and selected reflector components
• Fan covers and ventilation components
• Decorative housings and appliance panels

Surface finish, coating requirements, dimensional tolerances, and forming depth should be matched to the intended part to achieve a consistent production result.
