Description of material HOVADUR® K220:

HOVADUR® K220 is a thermally precipitation hardenable copper-nickel-silicon alloy with addition of chromium. In hardened condition, the alloy shows high electrical and thermal conductivity as well as great hardness and strength combined with good resistance to corrosion and abrasion. The alloy also shows excellent cold and warm forming. HOVADUR® K220 is applied in many cases which require a Be-free alloy.

Application examples HOVADUR® K220:

  • Moulds for metal casting as well as plastic injection
  • Cooling inserts, mould inserts and mould cores for solving thermal problems in plastic injection moulds
  • Cooling inserts in die casting moulds
  • Parts for plastic injection moulds produced by generative manufacturing processes
