When to use the CrN coating

PLASTIC MOULDS
This coating is suitable for application on plastic and rubber moulds, to protect them from corrosive wear. It has a low coefficient of friction and an excellent detaching power over moulded parts.
MECHANICAL APPLICATIONS
Its low deposition temperature and excellent adhesion to substrates make it particularly suitable for application on Copper Beryllium alloys and in general on materials which cannot be coated at the normal PVD coating temperatures.
CHIP REMOVAL TOOLS
It is also suitable for application on chip removal tools for the machining of Copper, Copper Beryllium alloys, Aluminium Titanium alloys or Ampco Bronze.
