SmCo
Magnets is made from samarium as rare earth
elements and cobalt.With the performance of high coercive
force, high energy product and highly resistant
to oxidation, they are widely used in motors'
ignition coils, vacuum deposition, sputtering,
magnetic resonance, magnetic separation,
micro-motors, gauges and other high efficient
compact devices.
By
manufacturing process, SmCo Magnets
are divided into Sintered SmCo Magnets and
Bonded SmCo Magnets.
