Description of material HOVADUR® CNCS:

HOVADUR® CNCS is a thermally precipitation hardenable copper-nickel-silicon alloy with addition of chromium. The material shows high electrical and thermal conductivity as well as great hardness and strength. These properties are combined with good resistance to corrosion and abrasion. Furthermore, the alloy is excellent for cold and hot forming. HOVADUR® CNCS is applied in many cases which require a Be-free alloy.

Application examples HOVADUR® CNCS:

  • Die casting pistons in cold chamber die casting machines
  • Cooling inserts in moulds
  • Moulds for non-ferrous metal casting (e. g. brass taps)
  • Be-free parts for resistance welding
  • Fittings, braces and fixing elements for high strain, especially for aerial wire and marine applications
