What are the differences between 3 series aluminum alloys 3003 3004 3104 3105 3A21？

The differences between 3003, 3004, 3104, 3105 and 3A21 alloys in the 3 series aluminum alloys are mainly reflected in their chemical composition, mechanical properties and application fields. The following is a detailed comparison of these alloys:

3003 aluminum alloy:

Chemical composition: aluminum (Al) 96.7%, manganese (Mn) 1.2%, magnesium (Mg) 0.05%-0.20%.

Mechanical properties: tensile strength 130-185 MPa, yield strength 55-140 MPa, elongation 20-30%, good formability, weldability, corrosion resistance, and good rust prevention.

Application areas: commonly used in tanks and tanks for liquid products, construction processing parts, construction tools, various lamp parts, and various pressure vessels and pipes for thin plate processing

3004 aluminum alloy:

Chemical composition: aluminum (Al) 97.9%, manganese (Mn) 1.0%, magnesium (Mg) 0.8%-1.3%.

Mechanical properties: tensile strength 160-205 MPa, yield strength 150 MPa, elongation 10-20%.

Application areas: used for all-aluminum can bodies, chemical product production and storage devices, thin plate processing parts, building baffles, cable ducts, sewer pipes, various lighting parts, etc.

3104 aluminum alloy:

Chemical composition: aluminum (Al) balance, manganese (Mn) 0.9-1.5%, magnesium (Mg) ≤0.30%.

Mechanical properties: tensile strength and yield strength data are not clearly provided in the search results, but usually 3104 alloy and 3004 alloy have similar compositions, high strength and easy processing.

3A21 aluminum alloy:

Composition: manganese is also the main alloying element.

Performance: similar to 3003 and 3105, with good anti-rust performance.

3003 and 3105 alloys have good formability and weldability, suitable for parts requiring these properties; 3004 alloy has higher strength than 3003, suitable for parts requiring higher tensile strength; 3104 alloy is similar to 3004 alloy in composition, has higher strength and is easy to process, suitable for a variety of industrial applications. The specific selection of these alloys depends on the required mechanical properties and application environment.
