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 0.13mm to 6.5mm, and the diameter spans from 80mm to 1000mm. 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 90MPa - 130MPa; elongation ≥ 25%. Excellent ductility — suitable for deep drawing and complex forming processes.
  • H14 State (Strain Hardened & Partially Annealed): Tensile strength 130MPa - 180MPa; elongation ≥ 5%. Higher strength — ideal for applications requiring better structural stability.

Frequently Asked Questions

Q What is 3003 aluminum circle used for?
3003 aluminum circles are widely used in kitchenware manufacturing (such as pots, pans, and pressure cookers), construction industry components, electronics and lighting products, as well as various packaging applications. Its excellent formability and corrosion resistance make it a preferred choice across these industries.
Q What are the available thickness and diameter ranges for 3003 aluminum circles?
The standard thickness ranges from 0.13mm to 6.5mm, and the diameter spans from 80mm to 1000mm. Customized specifications are also available to meet specific project requirements, including special thicknesses or diameters for precision components.
Q What temper/material states are available for 3003 aluminum circles?
3003 aluminum circles are available in a wide range of tempers, including O (annealed), H12, H14, H16, H18, H22, H24, H26, H32, and more. The choice of temper depends on the required mechanical properties such as strength, hardness, and ductility for your specific application.
Q What is the difference between O state and H14 state for 3003 aluminum circles?
The O state (annealed) offers a tensile strength of 90-130MPa with an elongation of approximately 25%, making it ideal for deep drawing and complex forming processes due to its excellent ductility. The H14 state (strain hardened and partially annealed) provides higher tensile strength of 130-180MPa with about 5% elongation, making it suitable for applications that require better structural stability.
Q What is the main alloying element in 3003 aluminum alloy?
The main alloying element in 3003 aluminum alloy is manganese (Mn), which accounts for 1.0%-1.5% of the composition. This addition of manganese significantly improves the alloy's strength compared to pure aluminum while maintaining excellent corrosion resistance and workability.
Q Can 3003 aluminum circles be supplied in custom sizes?
Yes. In addition to standard specifications, 3003 aluminum circles can be produced in customized sizes to meet specific project requirements. Both CC (Continuous Cast) and DC (Direct Chill Cast) types are available, providing flexibility in material properties and surface quality to suit different manufacturing needs.
