Boron Nitride Coatings are used when casting aluminium, magnesium, zinc and lead. They contain "white graphite", produce non-wetting and lubricating surfaces and prevent efficiently adhering or sticking of melts. Due to their very good separation efficiency boron nitride coatings are used for coating moulds and dies in gravity and low pressure die casting as well as for casting of ingots, e. g. as used in the magnesium remelting plants of Rauch Fertigungstechnik, Austria. Automatic ladles are coated with boron nitride coatings in the area of pressure die casting. Further they find application with the continuous casting, for example with Wagstaff™ Casting Systems.
