PERMANENT MAGNET FOR ELECTROMAGNETIC DEVICE AND METHOD OF MAKING |
摘要 |
Permanent magnets, devices including permanent magnets and methods for manufacture are described with the permanent magnet (12, 112) comprising, for example: iron-boron-rare earth alloy particulate having an intrinsic coercive force of at least about 1591 kiloamperes/meter (about 20 kiloOersteds) and a residual magnetization of at least about 0.8 tesla (about 8 kiloGauss), wherein the rare earth content comprises praseodymium, a light rare earth element selected from the group consisting of cerium, lanthanum, yttrium and mixtures thereof, and balance neodymium; and a binder bonding the particulate. |
