Abstract

Sintered age-hardenable permanent-magnet alloys containing Fe, Ni and Al and, optionally, other elements, are improved by adding 0.001-0.15 per cent B to the powder before sintering, for example, as a powdered alloy such as ferro-boron containing 2-50 per cent B. The magnet material may then be sintered in the range 1300-1340 DEG C. A suitable composition contains 5-40 per cent Ni, 3-20 per cent Al, 0.001-0.15 per cent B, remainder Fe with the usual impurities such as C, Mn, P, S, Cr, W and Mo up to 1.0 per cent in total. The material may also contain up to 40 per p cent Co, up to 20 per cent Cu, up to 10 per cent Ti, up to 3 per cent Si, up to 5 per cent of either or both of Ta and Nb, the content of Fe being at least 30 per cent. The invention is applicable to the production of anisotropic magnets. Specification 668,278 is reffered to.
