ETP copper (Cu-ETP)

ETP copper is the standard for electrical applications. With a conductivity of at least 100% IACS, Cu-ETP is the material of choice for busbars, contact elements, terminals and all components where maximum electrical conductivity counts.

  • Conductivity: min. 100% IACS
  • Easily solderable and weldable
  • Standard for electrical engineering
  • Material thicknesses: 0.2 – 6 mm
  • Use: contacts, busbars, terminals

Oxygen-free copper (Cu-OF)

Cu-OF contains no oxygen and is therefore especially suited to vacuum applications, high-frequency technology and environments where hydrogen embrittlement poses a risk. Its conductivity exceeds 101% IACS.

  • Oxygen-free – no risk of embrittlement
  • Conductivity: over 101% IACS
  • Vacuum-tight
  • Material thicknesses: 0.3 – 4 mm
  • Use: vacuum technology, RF technology

Cu-DHP (phosphorus-deoxidized copper)

Cu-DHP is the first choice when soldering or welding is required. Thanks to phosphorus deoxidation it contains no residual oxygen and is exceptionally easy to join thermally. Typical for heat exchangers and installation technology.

  • Excellent solderability and weldability
  • No residual oxygen
  • Good corrosion resistance
  • Material thicknesses: 0.3 – 5 mm
  • Use: heat exchangers, installation technology

Copper-zinc alloy

Brass (CuZn37 / CuZn39Pb3)

Brass is a copper-zinc alloy with good machinability and an attractive golden appearance. CuZn37 offers good formability, while CuZn39Pb3 is the free-machining alloy for the highest machinability. Typical for contacts, fittings and decorative elements.

  • CuZn37 – easily formable, corrosion-resistant
  • CuZn39Pb3 – free-machining alloy, highest machinability
  • Attractive golden appearance
  • Material thicknesses: 0.3 – 6 mm
  • Use: contacts, fittings, decorative trim
