1 Chemical Composition
3003 aluminium alloy is based on aluminium, with manganese as the main alloying element. Its typical chemical composition (by weight percentage) is as follows:
- Aluminium (Al): 96.8% – 99.0%
- Manganese (Mn): 1.0% – 1.5%
- Copper (Cu): 0.05% – 0.20%
- Iron (Fe): ≤ 0.70%
- Silicon (Si): ≤ 0.60%
- Zinc (Zn): ≤ 0.10%
- Other elements (total): ≤ 0.15%
This composition endows the alloy with balanced mechanical properties and corrosion resistance.
2 Common Specifications
The specifications of 3003 Aluminium Circle are highly flexible to meet diverse application needs. Generally, the thickness ranges from 0.13 mm to 6.5 mm, and the diameter spans from 80 mm to 1000 mm. Customized specifications can also be provided according to specific project requirements, such as special thicknesses or diameters for precision components.
3 Mechanical Properties
The mechanical properties of 3003 Aluminium Circle vary significantly with different processing states (hardness levels). Two typical states are as follows:
- O State (Annealed): Tensile strength 90 MPa – 130 MPa; elongation ≈ 25%. Excellent ductility — suitable for deep drawing and complex forming processes.
- H14 State (Strain Hardened & Partially Annealed): Tensile strength 130 MPa – 180 MPa; elongation ≈ 5%. Higher strength — ideal for applications requiring better structural stability.

Frequently Asked Questions
What is 3003 Aluminum Circle used for?
3003 Aluminum Circle is widely used in kitchenware manufacturing (such as pots, pans, and pressure cookers), the construction industry, electronics and lighting (such as LED lamp housings and reflectors), and the packaging industry. Its excellent formability and corrosion resistance make it a preferred material across these sectors.
What thickness and diameter range is available for 3003 Aluminum Circle?
Standard 3003 Aluminum Circles are available in thicknesses from 0.13 mm to 6.5 mm and diameters from 80 mm to 1000 mm. Custom specifications — including special thicknesses or diameters — can be produced to meet specific project requirements.
What tempers / material states are available for 3003 Aluminum Circle?
3003 Aluminum Circle is available in a wide range of tempers to suit different application needs, including O (fully annealed), H12, H14, H16, H18, H22, H24, H26, H32, and more. The O state offers maximum ductility for deep drawing, while H-series tempers provide increasing levels of strength and hardness.
What is the difference between CC and DC type 3003 Aluminum Circle?
CC (Continuous Casting) and DC (Direct Chill Casting) refer to two different manufacturing processes. DC cast material generally offers superior internal grain structure, higher purity, and better mechanical consistency, making it preferred for demanding applications. CC material is more cost-effective and suitable for general-purpose uses.
How does 3003 Aluminum Circle compare to 1060 or 1100 series aluminum circles?
Compared to 1060 or 1100 series aluminum circles, 3003 Aluminum Circle contains manganese (1.0%–1.5%), which gives it approximately 20% higher strength while maintaining good formability. It also offers better corrosion resistance, making it more suitable for applications that require a balance of strength and workability, such as cookware and pressure vessels.
Can 3003 Aluminum Circle be anodized or surface treated?
Yes. 3003 Aluminum Circle can be anodized, coated, or polished to enhance its surface appearance and corrosion protection. However, due to its manganese content, the anodized finish may appear slightly darker compared to higher-purity 1xxx series alloys. Surface treatments are commonly applied in lighting reflector and decorative applications.
