Do you know about aluminum alloy 3003? In this blog, we will explore the introduction of 3003 aluminum alloy, its chemical and physical properties, and related application areas.

Introduction to 3003 Aluminum Alloy:

3003 aluminum alloy is a widely used material in manufacturing. It belongs to the forged aluminum-manganese alloy series and therefore has strong corrosion resistance. In addition, its strength is not high (slightly higher than industrial pure aluminum) and cannot be strengthened by heat treatment, so cold working methods are used to improve its mechanical properties.

It has high plasticity in the annealed state, good plasticity when semi-cold work hardening, low plasticity when cold work hardening, good corrosion resistance, good weldability, and can be cut.

Properties of Aluminum Alloy 3003:

Its main chemical components include elements such as manganese, copper, iron, silicon and zinc. Among them, the content of manganese is relatively high, which can reach between 1.0 and 1.5. It is one of the important elements that constitute the anti-rust performance of this aluminum alloy.

In terms of physical properties, 3003 aluminum alloy has the following characteristics:

  1. The density is lower, about 2.73g/cm³, which is slightly higher than pure aluminum.
  2. The melting point is about 660°C, which is higher than that of pure aluminum.
  3. It has good ductility and weldability, can be stretched, bent, stamped, etc., and is easy to manufacture aluminum products of various shapes and structures.
  4. It has good corrosion resistance and is resistant to atmosphere, fresh water, sea water, food and other media. It is one of the more durable aluminum products.
  5. The tensile strength σb of this aluminum alloy is 140-180 MPa, and the conditional yield strength σ0.2 ≥ 115 MPa.


3003 Aluminum Alloy Uses:

  1. Aerospace field: Because 3003 aluminum alloy has good processing performance, corrosion resistance and mechanical properties, it is widely used in manufacturing aircraft skins, structural parts, engine components, etc.
  2. Construction field: aluminum alloy 3003 has good plasticity and strength and can be processed into various complex shapes and structures. Therefore, it is widely used in building curtain walls, doors and windows, railings, stairs, etc.
  3. Packaging container field: Because of its good anti-corrosion performance and beautiful surface, it is widely used in the field of packaging containers, such as empty food cans, beverage cans, etc.
  4. In addition to the above fields, 3003 aluminum alloy can also be used in petrochemical, electronics, medical equipment and other fields. For example, in the petrochemical industry, it can be used to manufacture pipelines, reactors and other equipment; in the electronic field, it can be used to manufacture radiators, housings, etc. for electronic components.

In addition, this grade of aluminum alloy is often used to make aluminum plates, which is easy to process and has good rust resistance. Color paint can be rolled on the surface of raw aluminum to make products of various colors.
