33131 - Alumina and aluminum production and processing

This industry comprises establishments primarily engaged in extracting alumina generally from bauxite ore; producing aluminum from alumina; refining aluminum by any process; and rolling, drawing, casting, extruding and alloying aluminum and aluminum-based alloy basic shapes.

• Exclusion(s)

  • pouring non-ferrous molten metal into moulds, or under pressure into dies, to form castings (See 33152 Non-ferrous metal foundries)

331313 - Primary production of alumina and aluminum^CAN

This Canadian industry comprises establishments primarily engaged in extracting alumina generally from bauxite or producing aluminum from alumina.

• Illustrative example(s)

  • alumina (aluminum oxide), refining from bauxite
  • aluminum basic shapes (e.g., bar, ingot, rod, sheet), made in primary aluminum plants
  • primary smelting of aluminum

  All examples

• Inclusion(s)

  • rolling, drawing, casting or extruding basic shapes, from aluminum produced in the same establishment

• Exclusion(s)

  • rolling, drawing, extruding or alloying purchased aluminum (See 331317 Aluminum rolling, drawing, extruding and alloying)

331317 - Aluminum rolling, drawing, extruding and alloying^CAN

This Canadian industry comprises establishments primarily engaged in rolling purchased aluminum ingots; further hot or cold-rolling to produce sheet, plate or foil; drawing aluminum alloys into products such as wire; extruding basic shapes; and alloying or re-alloying aluminum or aluminum alloys.

• Illustrative example(s)

  • aluminum basic shapes (e.g., bar, ingot, rod, sheet), made from purchased aluminum
  • aluminum foil and sheet, made by flat rolling purchased aluminum
  • aluminum wire and cable, made from purchased aluminum
  • aluminum, recovering from scrap or dross
  • insulated aluminum wire (e.g., apparatus, energy, coaxial, communication) made in aluminum wire drawing plants
  • molten aluminum, made from purchased aluminum
  • wire, aluminum, made in wire drawing plants

  All examples

• Inclusion(s)

  • drawing aluminum wire, whether or not the establishment further works the wire by such operations as insulating it
  • recovering aluminum from scrap

• Exclusion(s)

  • rolling, drawing, extruding or alloying aluminum produced in the same establishment (See 331313 Primary production of alumina and aluminum)
