i.
Alloys like
alnico or nipermag are very hard and are used in the production of permanent
magnets.
ii.
Permanent magnets
of these alloys are used in microphones, loudspeaker, ammeters, voltmeters,
etc.
iii.
Alnico is an
alloy of iron containing aluminium, nickel and cobalt. Nipermag is an alloy of
iron containing nickel, aluminium and titanium.
iv.
Hence, permanent
magnets prepared from these alloys are most suitable for use in industries.
