CrN (chromium nitride)

Easy care and tough.

CrN is characterised by a good combination of wear resistance and toughness,
which makes it ideal for “thicker” depositions (up to 6 µm).

Sample applications

  • replacement for hard chromium
  • machining, forming, and punching of nonferrous metals
  • casting dies (also plasma nitrided)
  • injection moulding inserts
