ABSTRACT:
A permanent magnetic alloy which is obtained by adding copper in amount of 0.5 to 6.2 wt% to the conventional Mn-Al-C alloy comprising 68.0 to 73.0 wt% of manganese, (1/10 Mn -- 6.6) to (1/3 Mn -- 22.2) wt% of carbon and the remainder aluminum and subjecting thus prepared alloy to warm plastic deformation in order to improve plasticity of the alloy.
