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.
