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 ranges from 90 MPa to 130 MPa, and elongation is approximately 25%. This state features excellent ductility, making it suitable for deep drawing and complex forming processes.
  • H14 State (Strain Hardened and Partially Annealed): Tensile strength is between 130 MPa and 180 MPa, with an elongation of about 5%. This state has higher strength, ideal for applications requiring better structural stability.

Frequently Asked Questions
Q What is 3003 Aluminum Circle and what are its main alloying elements?
3003 Aluminum Circle is a round disc-shaped product made from 3003 aluminium alloy, which uses manganese (1.0%–1.5%) as its primary alloying element. This composition gives the material excellent corrosion resistance, moderate strength, and outstanding formability, making it widely used across various industries.
Q What thickness and diameter ranges are available for 3003 Aluminum Circle?
Standard 3003 Aluminum Circles are available in thicknesses from 0.13mm to 6.5mm and diameters from 80mm to 1000mm. Custom sizes can also be manufactured to meet specific project requirements, including special thicknesses or diameters for precision applications.
Q What temper/material status options are available for 3003 Aluminum Circle?
3003 Aluminum Circle is available in a wide range of temper states including O (fully annealed), H12, H14, H16, H18, H22, H24, H26, H32, and more. The O state offers maximum ductility for deep drawing, while H14 provides a balance of strength and formability for structural applications.
Q What industries and products commonly use 3003 Aluminum Circle?
3003 Aluminum Circle is widely used in kitchenware manufacturing (pots, pans, cookware), the construction industry, electronics and lighting (reflectors, lamp housings), and the packaging industry. Its excellent formability and corrosion resistance make it a preferred choice for these sectors.
Q What is the difference between CC and DC type 3003 Aluminum Circle?
CC (Continuous Casting) and DC (Direct Chill Casting) refer to the two main production methods. DC casting generally produces material with more uniform grain structure and better mechanical properties, making it suitable for demanding applications. CC casting is more cost-effective and widely used for general-purpose products. Both types are available in our 3003 Aluminum Circle range.
Q Can 3003 Aluminum Circle be customized for special project requirements?
Yes, 3003 Aluminum Circle can be fully customized in terms of thickness, diameter, temper state, and surface finish to meet specific project requirements. Whether you need precision components with tight tolerances or large-format discs for industrial use, customized specifications are available upon request.
