Amorphous Magnetic Materials and their Applications0 pages

Amorphous Magnetic Mc

There is a magnetic metal material with very unique characteristics that does not have a

crystalline structure. At Toshiba Materials, we focused on the excellent magnetic

characteristic of this amorphous magnetic alloy and started research and development years

ago, anticipating future applications and need for such a product. This Amorphous alloy was

called "alloy of dreams" at the time when we started our research but in recent years, it has

and is finding application in electrical products (desk top computer, copying machine, printer

etc.) very close to you. Amorphous magnetic parts made it possible to reduce energy

consumption, minimize electronic circuit noise for electrical products with a product

considered environmentally friendly.

Amorphous Alloy

Amorphous alloy is a general term for a metal with a non-crystalline structure of atoms.

Regular alloys have a uniformly formed metallic crystalline structure, but for amorphous

alloys, the atoms are distributed randomly. As a result of this random atomic distribution, the

magnetic properties of amorphous alloys are anisotropic. Also, in addition to an increase of

electrical resistivity, thin ribbons are directly made so that the eddy current losses will be

small and the magnetic characteristics will be significantly improved.

At Toshiba Materials, we manufacture a Cobalt based amorphous alloy by the liquid rapid

cooling method. This method of rapid cooling, at a rate of about 1 million degrees per second,

prevents the metal from solidifying in an amorphous structure rather than in its normal

ordered crystalline structure.
