Semi-finished copper products: bars, sheets, tubes and wire

Copper: CW024A – CW004A

Used since the ancient Romans as water pipes and at different times in various fields: plumbing, electrical and thermal capacity having regard to its high conductivity; construction for gutters, rainwater pipes, roofing, artistic as ductile and malleable. It is an important component in many other non-ferrous metals alloys.

Its chemical symbol is Cu.

Divided into two main compositions according to use:

Cu DHP UNI EN 12449 CW024A

pipes for general use and for industrial use and plumbing

  • soft annealed pipes in rolls diameter mm 3×0, 5 mm. 4×0,5
  • soft annealed pipes in rolls diameter from mm 6×1 to mm 22×1 (EN 1057 also marked for gas and water for buildings Directive)
  • soft annealed pipes in rolls diameter mm. 8-10-12-14-16 mm thick. 1.5
  • hard straight pipes from mm 5×1 mm to mm 54×1, 5

Cu ETP UNI EN 13601 CW004A

particularly suitable for use with high electrical conductivity, are available ready-to-stock:

  • round bars from diameter 5 mm to diameter 130
  • square bars from mm 8×8 to 120×120
  • flat bars from mm 10×2 to 200×20

Cu ETP UNI EN 13602 CW004A
