Title:
PERMANENT MAGNET ALLOY
Document Type and Number:
Japanese Patent JPS58157938
Kind Code:
A
Abstract:
PURPOSE: To obtain a permanent magnet alloy having increased and stabilized coercive force by substituting Mn for a specified amount of Fe in an alloy consisting of specified percentages of a rare earth metal, Co, Cu, Zr, Zn and Fe.
CONSTITUTION: A permanent magnet alloy is obtd. by substituting Mn for 8W 10wt% Fe in a blended composition consisting of, by weight, 22W28% R (R is 1 or ≥2 kinds of rare earth metals such as Sm and Ce), 36W58% Co, 8W12% Cu, 1W3% Zr, 1W3% Zn and 10W18% Fe. Thus, superior coercive force can be provided stably.
