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.

• 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

• Inclusion(s)

  • drawing copper wire (whether or not the establishment further works the wire by such operations as insulating it) and recovering copper from scrap

• Exclusion(s)

  • casting copper (See 33152 Non-ferrous metal foundries)
  • insulating purchased copper wire and cable (See 335920 Communication and energy wire and cable manufacturing)
