A Comparison of 3003 and 3004 Aluminum Alloys

Aluminum alloys 3003 and 3004 are commonly used aluminum alloys with notable differences in their composition, properties, and applications. 

1. Composition:

3003 Aluminum Alloy:

• Prominent manganese content: 1.0-1.5% manganese

• Applications: Chemical containers (e.g., nitric acid, phosphoric acid), insulated aluminum jacketing for pipes, etc.

3004 Aluminum Alloy:

• Prominent manganese and magnesium content: 1.0-1.5% manganese, 0.8-1.3% magnesium

• Applications: Coated coils, painted aluminum coils, aluminum-magnesium-manganese plates, roofing materials, etc.

2. Performance Differences:

3003 Aluminum Alloy:

• Corrosion resistance: The addition of manganese enhances its resistance to corrosive substances, making it suitable for containers exposed to chemicals like nitric acid and phosphoric acid, as well as insulation for pipes.

• Excellent welding and stamping properties: Widely used in the production of outer casings for new energy vehicle power batteries.

• Good heat dissipation: Applied in heat exchanger products such as fins and water-cooling plates.

• Excellent processing and painting capabilities: Often fabricated into sheet metal components. Highly utilized in the construction industry, especially for curtain wall materials.

3004 Aluminum Alloy:

• Higher strength compared to 3003: Suitable for components requiring higher strength.

• Good formability, weldability, and corrosion resistance: It cannot be heat treated for further strengthening. Primarily used in the production of chemical equipment, building panels, various lighting components, beverage cans, surfboards, lamp caps, etc.

• Aluminum foil made from 3004 alloy is commonly used in food-grade containers like disposable aluminum cups, aluminum lunch boxes, and pre-packaged food packaging.

Conclusion:

In summary, the composition and properties of aluminum alloys 3003 and 3004 exhibit distinct differences. The 3003 alloy, with its enhanced corrosion resistance, excellent welding and stamping properties, and good heat dissipation, finds application in various industries. On the other hand, the 3004 alloy, known for its higher strength, formability, weldability, and corrosion resistance, is commonly used in the production of coated coils, roofing materials, chemical equipment, and food-grade containers. Understanding these differences aids in selecting the appropriate aluminum alloy for specific applications.
