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:

Al (Aluminium): 96.8% – 99.0%  |  Mn (Manganese): 1.0% – 1.5%  |  Cu (Copper): 0.05% – 0.20%  |  Fe (Iron): ≤ 0.70%  |  Si (Silicon): ≤ 0.60%  |  Zn (Zinc): ≤ 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 Circle is widely used in kitchenware manufacturing (such as pots, pans, and cookware lids), the construction industry, electronics and lighting applications, and the packaging industry. Its excellent formability and corrosion resistance make it a preferred material for deep-drawn products.
Q What thickness and diameter options are available for 3003 Aluminum Disc?
Standard 3003 Aluminum Discs are available in thicknesses ranging from 0.13mm to 6.5mm and diameters from 80mm to 1000mm. Custom specifications — including special thicknesses or diameters for precision components — can also be produced upon request.
Q What temper/material status options does 3003 Aluminum Circle come in?
3003 Aluminum Circle is available in a variety of tempers to suit different application requirements, including O, H12, H14, H16, H18, H22, H24, H26, H32, and more. The O (annealed) state offers maximum ductility, while H-series states provide progressively higher strength levels.
Q What is the difference between CC and DC type 3003 Aluminum Circles?
CC (Continuous Casting) and DC (Direct Chill Casting) refer to the manufacturing process used to produce the aluminum. DC-cast material generally offers more uniform microstructure and better surface quality, making it suitable for demanding deep-drawing applications, while CC material is cost-effective for standard uses.
Q What are the key mechanical properties of 3003 Aluminum Circle in the O and H14 states?
In the O (annealed) state, the tensile strength is 90–130 MPa with an elongation of approximately 25%, offering excellent ductility for deep drawing. In the H14 state (strain hardened and partially annealed), tensile strength increases to 130–180 MPa with an elongation of about 5%, providing better structural stability for more demanding applications.
Q Why is manganese added to 3003 aluminum alloy?
Manganese (1.0%–1.5%) is the primary alloying element in 3003 aluminum. It improves strength compared to pure aluminum (1xxx series) while maintaining excellent corrosion resistance and workability. This balance makes 3003 alloy ideal for applications that require both formability and durability, such as cookware and industrial components.
