Soft Magnetic Alloy with
High Magnetic Flux Density
Permendur
Overview
Permendur is an Fe-Co alloy with high saturation magnetic flux density. It contributes to miniaturization, high output and rapid response for motors, actuators, etc.
Features
・Excellent magnetic properties, e.g. high saturation magnetic flux density (Bmax=2.3T).
・Hitachi Metals can provide raw materials (sheet and bar) and a laminated motor core.
