SmCo magnet is a high performance low temperature coefficient permanent magnet made of samarium and cobalt and other rare earth elements.

The main advantage of SmCo magnets: high magnetic capability, excellent temperature stability, superior corroding-resistance and oxideizing-resistance.

The characteristic and application of SmCo magnets:

• SmCo permanent magnet has high magnetic energy product and high coercive force. Its properties are better than AlNiCo, ferrite permanent magnet. Its maximum magnetic energy product is up to 239KJ/m3 (30MGOe), which is three times than AlNiCo8 permanent magnet, eight times than ferrite permanent magnet (Y40). So the permanent magnetic component made from SmCo permanent magnets is small, light and stable in property.

• It is widely used in electronic acoustic and telecommunication appliance, electronic motor, measure meter, peg-top, electronic watch, microwave appliance, magnetic machine, sensor, trnsducers, instruments, positional detector, generators, radar and other static or dynamic magnetic routes.

• The curie temperature of the SmCo permanent magnet is high and its temperature coefficient is little. So it is suitable for using at 300°C high temperature.

• SmCo permanent magnet is hard and bristle. Its rigidity strength, tensile and press strength are low. So it is not suitable for framework.

• The main ingredient of SmCo permanent magnet is metal Cobalt (Co≥99.95%). So its price is high.

• SmCo permanent magnet needn't to be coated because it is difficult to be eroded and oxidized.
