Magnetic properties of mischmetal-(Co, Cu, Fe, Mg) alloys.
IEEE Trans Magn 1979 Nov; 15(6):1757-1759
To relieve the dependence for critical and strategic minerals through conservation and substitution, the Bureau of Mines investigated alloys containing mischmetal (mm), cobalt, copper, magnesium, and iron for use in permanent magnets in place of the scarce samarium-cobalt alloys. The magnetic properties of selected mm-co-cu-mg and mm-co-cu-mg-fe alloys were evaluated. Magnets were fabricated by powder metallurgy that consisted of arc-melting the metals, crushing and grinding the resultant alloy, alining and compacting the powder, and sintering the green compacts.
