Aluminum alloys are typically categorized into three groups: wrought non-heat treatable, wrought heat treatable, and casting alloys.


List of Common Aluminum Alloys and Their Applications

  1. 1100: Soft, non-heat treatable alloy with excellent corrosion resistance; used in electrical work and food handling.

  2. 3003: Non-heat treatable alloy with good strength and corrosion resistance; used in everyday products like cookware and hardware.

  3. 3004: Similar to 3003, with added strength due to magnesium; used in storage tanks and cookware.

  4. 3105: Similar to 3003, with slightly higher strength; used in building applications like roofing and siding.

  5. 5052: Strongest non-heat treatable alloy; used in marine applications and fuel tanks.

  6. 6061: Heat treatable alloy with excellent strength and versatility; used in architecture and construction.

  7. 6063: Heat treatable alloy with superior surface finish; used in electrical components and door frames.

Conclusion

Understanding the properties and applications of various aluminum alloys can help industries make informed decisions when selecting the right material for their products. Aluminum's versatility, strength, and sustainability make it an ideal choice for many applications across various industries.
