What is permendur?

YEP^™-2V is Fe-Co-V soft magnetic alloy, which is well-known as permendur, where vanadium is added to improve workability.
This alloy has high saturated magnetic flux density (approximately 2.3T) and high permeability. It contributes to realize compact, lightweight, high-power and high responsive products such as motors and actuators.
Proterial, Ltd. provides YEP^™-2V in various forms such as strip, bar and wire.
