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. Establishments engaged in secondary activities, such as rolling, drawing , casting or extruding basic shapes, from aluminum produced in the same establishment, are included.

• 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

• 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. Establishments primarily engaged in drawing aluminum wire, whether or not the establishment further works the wire by such operations as insulating it, are included. Establishments primarily engaged in recovering aluminum from scrap are also included.

• 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

• Exclusion(s)

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