Flint is produced from a mischmetal and iron melt by permitting the alloy melt to cool in a mold at a slow enough rate that, as the solidification point of the melt is approached, its temperature is maintained at 800 DEG -600 DEG C for at least 10 minutes. The alloy melt is subsequently extruded and the extrudate is subjected to a heat treatment at temperatures from 370 DEG -470 DEG C for 1/2 to 4 hours, the heat treatment being discontinued before the limit value of the thermodynamic equilibrium has been reached.
