What is 3003 aluminum?

3003 aluminum profile belongs to AL-Mn system alloy, i.e. aluminum-manganese alloy. This alloy is widely used in industry, especially as rust-proof aluminum.

Its composition:

Aluminum (Al):

The content of aluminum is up to 98% and it is the main metal of 3003 aluminum alloy. Therefore 3003 also belongs to one kind of pure aluminum alloy.

Manganese (Mn):

Manganese is the main alloying element in 3003  and is used to improve the strength and corrosion resistance of the alloy. It content ranges from 1.0% to 1.5%.

Silicon (Si):

Silicon is another alloying element that contributes to the properties of the alloy, albeit at relatively low levels. The content of silicon is around 0.60%

Its product properties:

Strength: Although 3003 aluminum alloy is slightly stronger than industrially pure aluminum, it cannot be strengthened by heat treatment.

Plasticity: In the annealed condition, 3003 aluminum alloy has high plasticity. When cold work hardened, the plasticity is low.

Corrosion resistance: 3003 aluminum alloy has good corrosion resistance.
Weldability: it has good welding performance, and can be gas welding, argon arc welding, spot welding and other welding methods.

Uses of 3003 aluminum:

• It is because of its good formability, weldability and corrosion resistance. It is widely used in several industries. It is mainly used for the requirement of high moldability and good weldability.
• It is able to be used for low load parts working in liquid or gaseous media. Such as fuel tanks, gasoline or lubricating oil conduits, and various liquid containers.
• It will be used in chemical instruments, thin plate processing parts. Deep drawing or spinning concave utensils, welded parts, heat exchangers, clock faces and disk faces, nameplates, kitchen utensils and other products.

In addition, it can be used in the production of rivets, kitchenware, food and chemical product handling and storage devices, tanks.

Processing and Handling:

Since 3003 aluminum alloy cannot be strengthened by heat treatment, its strength is usually increased by cold deformation. Annealing is its only form of heat treatment.

Final Summary:

3003 Aluminum is used as an aluminum alloy with aluminum as the main body. It has strong corrosion resistance and safety. Therefore it is used by people in food tools. After the above introduction I believe you have learned its role in daily life.
