Mechanical Properties

The mechanical properties of 3003 Aluminum Sheet are closely related to its processing state (temper), and different tempers are designed to meet diverse strength and ductility requirements. The following are the key mechanical performance indicators of typical tempers:

O State (Full Annealed)
Tensile strength (σb): 90 – 130 MPa | Yield strength (σ0.2): ≤ 40 MPa | Elongation (δ): ≥ 25%
This temper has the best ductility, suitable for complex forming processes such as deep drawing, bending, and stamping.
H14 State (Strain Hardened + Partial Annealed)
Tensile strength (σb): 130 – 180 MPa | Yield strength (σ0.2): 110 – 150 MPa | Elongation (δ): ≥ 5%
Balances strength and formability, widely used in structural parts requiring moderate strength.
H18 State (Full Strain Hardened)
Tensile strength (σb): ≥ 180 MPa | Yield strength (σ0.2): ≥ 160 MPa | Elongation (δ): ≥ 3%
With the highest strength, it is suitable for load-bearing components that do not require secondary forming.

Frequently Asked Questions (FAQ)
What is 3003 alloy aluminium sheet mainly used for?
3003 aluminium sheet is widely used across multiple industries including construction, automotive and transportation, kitchenware and daily necessities, industrial equipment, and packaging. Its excellent corrosion resistance and formability make it a versatile choice for both structural and decorative applications.
What tempers are available for 3003 aluminium sheet?
3003 aluminium sheet is available in a wide range of tempers including O, H12, H14, H16, H18, H22, H24, H26, and more. Each temper offers different combinations of strength, hardness, and ductility to suit specific application requirements.
What thickness range does 3003 aluminium sheet come in?
3003 aluminium sheet is available in thicknesses ranging from 0.2 mm to 200 mm, and widths from 50 mm to 1200 mm, providing flexibility for a broad range of engineering and manufacturing projects.
What is the difference between CC and DC processing for 3003 aluminium?
CC (Continuous Casting) and DC (Direct Chill Casting) are two different manufacturing processes. DC casting generally produces sheets with higher mechanical properties and better surface quality, making it suitable for demanding applications, while CC casting is more cost-effective and suitable for general-purpose uses.
Which temper should I choose if I need to deep draw or bend the aluminium sheet?
For complex forming processes such as deep drawing, bending, or stamping, the O state (fully annealed) is recommended. It offers the best ductility with an elongation rate of ≥ 25% and a low yield strength of ≤ 40 MPa, making it highly workable.
How does the H18 temper differ from H14 in terms of mechanical performance?
The H18 temper (fully strain hardened) provides the highest strength with a tensile strength of ≥ 180 MPa and yield strength of ≥ 160 MPa, but lower elongation (≥ 3%). In contrast, H14 offers a balanced combination of moderate strength (130–180 MPa tensile) and better formability (elongation ≥ 5%), making it more suitable for structural parts that require some degree of shaping.
