Copper (Cu) is a soft reddish metal that stands out for its thermal and electrical conductivity. It is easy to process mechanically and is resistant to corrosion, because the effect of humidity and carbon dioxide in the air quickly covers it with a thin layer of greenish copper carbonate called verdigris, and this effectively protects it against deeper oxidation.

Thanks to its corrosion resistance, it can be used for:

  • roofing, eaves and other roof accessories;
  • pipes for carrying industrial gases;

electrical conductivity:

  • electrical wiring for industrial uses (electric motors, generators) and for supplying electricity in homes, etc.;
  • electronic components, integrated circuits;

for thermal conductivity:
