Melt Spun/Jet Milled Isotropic Bonded Magnets
By Dr. John Ormerod
Technical Adviser / Magnet Applications
The principle of melt-spinning consists of melting the alloy or elements in a tube under vacuum or inert gas. The melt, under inert gas pressure, is sprayed through an orifice in the tube onto a rotating, water-cooled copper wheel or disc. Cooling rates in excess of 1,000,000 C/sec. are achieved which produces an alloy with an amorphous or fine grained nanocrystalline structure.
