Magnetic Circuit Made of Nanocrystalline Soft Magnetic

Alloy 5 (FeNbCuMoCoBSi)

Nanocrystalline Soft Magnetic Alloy 5 is a new material got by high speed melt-quench. Advantages of magnetic circuits made of this material are high induction at low coercive force, low losses for remagnetization at high frequencies, near-zero magnetostriction.

B type alloy is used for magnetic circuit production.

B type alloy has a round hysteresis loop, high permeability in low fields.

A magnetic circuit made of this material is used in measuring current transformers, chokes, pulse and radio-frequency transformers.
