BONDED MAGNET WITH LOW LOSSES AND EASY SATURATION

摘要

PURPOSE: A bonded magnet is provided for low coercivity and low loss upon aging. CONSTITUTION: A bonded isotropic magnet contains a composition comprising from about 5 to 25% rare earth metal, from about 0.5 to about 4.5% boron, from about 0.5 to about 3.0% niobium, and the balance principally of iron. More than 95% of rare earth metal consists of neodimum and praceodimum.
