3003 Aluminum Strip

3003 aluminum strip is a manganese-alloyed aluminum material used where manufacturers need a practical balance of formability, corrosion resistance, and moderate strength. Haomei Aluminum supplies 3003 strip for stamping, radiator fins, HVAC components, trim parts, and other fabricated products, with customized widths, thicknesses, tempers, and coil weights available for production requirements.

Our 3003 strip is available in coils, slit coils and custom narrow-width formats. Common tempers include H14, H16 and H18, selected according to forming depth, surface requirements and final-part strength.

Why Choose 3003 Aluminium Strip?

For projects where maximum electrical conductivity is the priority, please see our 1050 aluminum strip and 1060 aluminum strip options.

3003 H14, H16 and H18 Aluminum Strip

The temper has a direct effect on how the strip behaves during fabrication. Haomei can supply different tempers according to the forming method, dimensional requirements and finished-part performance.

3003 H14 Aluminum Strip

3003 H14 aluminum strip is a half-hard temper commonly selected for general fabrication, bending and moderate forming. It provides a useful balance between strength and workability and is often considered where the strip must hold its shape after forming.

3003 H16 Aluminum Strip

3003 H16 is harder than H14 and can be considered where additional strength or rigidity is required without moving to the hardest available temper.

3003 H18 Aluminum Strip

3003 H18 aluminum strip is a harder temper intended for applications where higher strength and dimensional stability are more important than maximum formability.

3003 Aluminum Strip for Stamping

Haomei Aluminum supplies 3003 aluminum strip for stamping where stable material behavior is essential for repeatable production. Depending on the geometry of the part, H14 or softer tempers may be suitable for moderate forming, while H18 may be used for shallow stamping or parts that need a firmer final profile.

Common stamped products include:

For deeper drawing requirements, see our aluminum circle sheet for deep drawing range.

3003 Aluminum Strip for Radiator Fin Applications

3003 aluminum strip for radiator fin applications is valued for its combination of formability, corrosion resistance and thermal performance. It can be supplied in carefully controlled thicknesses and slit widths for heat-transfer component production.

Typical heat-exchange applications include:

Fin stock requirements vary significantly by equipment design. Before ordering, please confirm whether your process requires bare aluminum, coated material, specific fin temper, lubrication compatibility or a defined surface roughness.

For related materials, please review our aluminum fin stock pages.

Other Applications of 3003 Aluminum Strip

Beyond radiator and stamping applications, 3003 strip can be used in a range of fabricated products where moderate strength, corrosion resistance and workability are required.

HVAC and Duct Components

3003 is used in components for heating, ventilation and air-conditioning systems where corrosion resistance and easy fabrication are important.

Automotive and Architectural Trim

Narrow strip can be slit for trim profiles and formed components where appearance, corrosion resistance and consistent dimensions matter.

Food Service and Processing Equipment

3003 is also associated with food and chemical handling applications because of its combination of workability and corrosion resistance.

General Industrial Fabrication

The material can be cut, bent, formed and assembled into a variety of industrial components where the strength level of high-strength structural alloys is not required.

Frequently Asked Questions – 3003 Aluminum Strip

What is 3003 aluminum strip?

3003 aluminum strip is a rolled aluminum-manganese alloy supplied in coil or narrow slit-coil form. It has good corrosion resistance, formability and weldability, making it suitable for HVAC, stamping, trim, shutters, transformer parts and general fabrication.

Is 3003 stronger than 1100 aluminum?

Yes. 3003 contains manganese and generally provides higher strength than 1100 aluminum while retaining good workability. It is often selected when a project needs better rigidity than pure aluminum grades can provide.

What is the difference between 3003 H14 and 3003 H18 aluminum strip?

3003 H14 is half-hard and offers a balance of formability and strength. 3003 H18 is full-hard, providing greater stiffness but less ability to withstand severe bending or deep forming. The right choice depends on the final part design and manufacturing process.

Can 3003 aluminum strip be used for stamping?

Yes. 3003 aluminum strip is commonly used for stamping, particularly in suitable tempers such as O or H14. For deep or complex stamped parts, temper selection should be based on the drawing depth, bend radius and tooling conditions.

Can you supply custom-width 3003 aluminum narrow strip?

Yes. Haomei Aluminum can supply 3003 aluminum narrow strip and slit coil in customized widths. Please provide your required thickness, width tolerance, coil ID, edge condition, coil weight and application details.

Is 3003 suitable for radiator fins?

3003 is used in certain radiator-fin and heat-transfer applications because it combines corrosion resistance and formability. However, the exact temper, thickness, coating and surface requirements should be selected according to the fin-forming process and heat-exchanger design.
