Aluminum 3003

Aluminum 3003 is a popular alloy that offers customers very good atmospheric corrosion resistance and moderate strength. Aluminum 3003 offers good machinability for aluminum alloys, though it is not heat treatable.

Unlike other aluminum alloys, 3003 is weldable by conventional welding methods. It also takes cold and hot working well and has generally better mechanical properties when compared to 1000 series aluminum alloys.

Because of its unique properties, Aluminum 3003 is in use for a number of different applications including:

  • Chemical equipment
  • Ductwork
  • Cooking utensils
  • Pressure vessels
  • Eyelet stock
  • Ice cube trays
  • Garage doors
  • Refrigerator panels
  • Gas line and tanks
  • Heat exchangers
  • Drawn and spun parts
  • Roofing, sidings, acoustic ceilings, and corrugated sheets

To be considered Aluminum 3003, an alloy most contain a certain chemical composition that includes:

  • Al 98.6%
  • Mn 1.2%
  • Cu 0.12%

The high-quality Aluminum 3003 stocked and sold by Continental Steel meets or exceeds a number of different leading specifications including, ASME, ASTM, AWS, MIL-Spec, QQ, SAE, and UNS.

Continental Steel supplies Aluminum 3003 in a wide variety of shapes and sizes including tube, pipe, and sheet. To discover if Aluminum 3003 is right for your next project, please contact an aluminum alloy expert at Continental Steel today.
