Primary metal manufacturing

331 - Primary metal manufacturing

This subsector comprises establishments primarily engaged in smelting and refining ferrous and non-ferrous metals from ore, pig or scrap in blast or electric furnaces. Metal alloys are made with the introduction of other chemical elements. The output of smelting and refining, usually in ingot form, is used in rolling and drawing operations to produce sheet, strip, bars, rods and wire, and in molten form to produce castings and other basic metal products.

  • Exclusion(s)

    • manufacturing metal forgings or stampings(332)

3314 - Non-ferrous metal (except aluminum) production and processing

This industry group comprises establishments primarily engaged in smelting, refining, rolling, drawing, extruding and alloying non-ferrous metal, except aluminum.

  • Exclusion(s)

    • smelting, refining, rolling, drawing, extruding and alloying aluminum (See 3313 Alumina and aluminum production and processing)

33142 - Copper rolling, drawing, extruding and alloying

This industry comprises establishments primarily engaged in rolling, drawing, extruding and re-alloying copper, brass, bronze and other copper-based alloys, to produce products such as plates, sheets, strips, bars, wire and tubing, and specialty alloys. Establishments primarily engaged in drawing copper wire (whether or not the establishment further works the wire by such operations as insulating it), and in recovering copper from scrap, are included.

331420 - Copper rolling, drawing, extruding and alloying

This Canadian industry comprises establishments primarily engaged in rolling, drawing, extruding and re-alloying copper, brass, bronze and other copper-based alloys, to produce products such as plates, sheets, strips, bars, wire and tubing, and specialty alloys. Establishments primarily engaged in drawing copper wire (whether or not the establishment further works the wire by such operations as insulating it), and in recovering copper from scrap, are included.

  • Illustrative example(s)

    • brass products, made by rolling, drawing, extruding or alloying purchased metal
    • bronze products, made by rolling, drawing, extruding or alloying purchased metal
    • copper alloys (e.g., brass, bronze), made from purchased metals and copper-based alloys
    • copper refining, secondary (i.e., from purchased metal or scrap)
    • foil, copper and copper alloy, made by rolling purchased metal or scrap
    • tubing, copper and copper alloy, made from purchased metal or scrap
    • wire, copper and copper alloy, made in wire drawing plants

    All examples

  • Exclusion(s)

    • manufacturing copper and copper alloy products in a smelter or refinery (See 331410 Non-ferrous metal (except aluminum) smelting and refining)
    • casting copper (See 33152 Non-ferrous metal foundries)
    • insulating purchased copper wire and cable(335920)
