Abstract
PURPOSE: To enhance the magnetic characteristics of the resulting permanent magnet material by adding a small amount of Sn to an R-Co-Cu-Fe magnet alloy contg. a rare earth element R.
CONSTITUTION: This permanent magnet material has a composition consisting of, by wt., 20W35% R (≥1 kinds of rare earth elements), 5W15% Cu, 3W20% Fe, 0.05W3% Sn and the balance essentially Co or further contg. ≤5% of one or more amount Ti, V, Zr, Nb, Mn, Cr, Hf and Ta. This material has superior magnetic characteristics, that is, superior coercive force, residual magnetic flux density and magnetic energy product.
