ANISOTROPIC PERMANENT MAGNETS OF MN-AL-C ALLOYS Abstract of the Disclosure An anisotropic permanent magnet of an Mn-Al-C alloy containing 68.0% to 73.0% by weight of manganese, (1/10Mn-6.6) % to (1/3Mn-22.2) % by weight of carbon and the remainder aluminum, which alloy is rendered anisotropic by deforming it plastically at a temperature of 530°C to 830°C. The permanent magnet has excellent mechanical characteristics and magnetic properties such that the (BH)max is above 4.8 x 106 G.Oe up to about 9.2 x 106 G.Oe in its bulk state.
