  1. Weldability:

3003 and 3004 aluminum alloys have good weldability and can be subject to conventional welding processes, suitable for products requiring welding processing.

  1. Good forming and processing performance:

3003 and 3004 aluminum alloy have good forming and processing performance, can be formed by die-casting, deep drawing, stretching and other processing technology, suitable for a variety of complex shapes of product manufacturing.

  1. Wide range of application:

3003 and 3004 aluminum alloys are general-purpose aluminum alloys, applicable to the manufacture of construction materials, automotive parts, electronic product shells, aerospace field and other fields.

 

The differences between 3003 aluminum alloy and 3004 aluminum alloy are mainly reflected in the following aspects:

  1. Chemical composition:

3003 aluminum alloy contains 0.1-0.2% manganese, 0.6% iron, 0.05-0.2% copper, 0.1% zinc, and residual aluminum; while 3004 aluminum alloy contains 0.8-1.3% manganese, 0.7% iron, 0.25% copper, 0.25% zinc, and residual aluminum. It can be seen that the manganese content in 3004 aluminum alloy is higher, so it has better strength and corrosion resistance.

  1. Mechanical properties:

The tensile strength of 3003 aluminum alloy is 110-130 MPa, the yield strength is 85 MPa, and the elongation is 5-20%; while the tensile strength of 3004 aluminum alloy is 190-220 MPa, the yield strength is 150 MPa, and the elongation is 8-20%. It can be seen that the mechanical properties of 3004 aluminum alloy is higher.

  1. Machining performance:

Because of the higher manganese content in 3004 aluminum alloy, it has better machining performance and can be more easily formed and processed, which is suitable for the manufacture of products requiring higher precision.

 

Overall, there are some differences between 3003 and 3004 aluminum alloys in terms of chemical composition, mechanical properties and machining properties, and the specific choice of which alloy depends on the specific application requirements and performance needs.
