Nanocrytalline is amorphous ribbon (non-crytalline) obtained by rapid quenching at one million ℃/second from the molten metal consisting of Fe, Si, B and small amounts of Cu and Nb. These crystallized alloys have grains which are extremely uniform an small, about 10 nanometers in size, Amorphous metals which contain certain alloy elements show superior soft magnetic properties through crystallization. Therefore cores made in Nanocrystalline are much more superior than the other soft magnetic materials.
