What is 3003 aluminum circle disc?

3003 aluminum disc refers to an aluminum disc or disc made of 3003 aluminum alloy. Aluminum circles are widely used in various industries due to their excellent properties, including formability, corrosion resistance, thermal conductivity, etc. The symbol “3003” represents the aluminum alloy composition, where “3” represents the addition of manganese as the main alloying element. 3003 aluminum alloy is mainly composed of aluminum with manganese (Mn) as the main alloying element. It usually contains small amounts of other elements such as copper (Cu) and iron (Fe).

3003 aluminum disc chemical composition

The 3003 aluminum alloy is a wrought aluminum-manganese alloy with good formability and moderate strength. Its chemical composition is as follows:

Aluminum (Al): 96.8% – 99.0%
Manganese (Mn): 1.0% – 1.5%
Copper (Cu): 0.05% – 0.20%
Iron (Fe): 0.70% max
Silicon (Si): 0.60% max
Zinc (Zn): 0.10% max
Others: Each element (single): 0.05% max
Others: Total: 0.15% max

3003 aluminum circle temper

The state of the 3003 aluminum circle alloy is different, which will also affect its mechanical properties. The commonly used states of aluminum circle 3003 are:

3003 O aluminum circle (annealed): This is the softest state of 3003 aluminum. It is fully annealed for lowest strength and highest ductility. The 300 O temper is suitable for applications requiring forming and deep drawing.

3003 H12 aluminum circle: This temper is the strain hardened (cold worked) version of the 3003 aluminum circle. The H12 temper offers a balance of strength and formability making it suitable for medium forming operations.

3003 H14 aluminum circle: Also a strain hardening temper, H14 offers higher strength compared to H12. It is achieved by further cold working after H12 tempering. H14 is typically used in applications requiring higher strength and moderate formability.

3003 H16 aluminum circle: This temper is similar to H14 but has higher strength due to added cold working. H16 3003 aluminum pans are suitable for more demanding forming operations and applications requiring increased strength.

3003 H18 aluminum circle: The H18 status represents a high strength version of the 3003 aluminum circle. It undergoes extensive cold working to achieve its level of strength.
