Cobalt Magnets

Samarium Cobalt Magnets alloys (generally written as SmCo5 or SmCo series 1:5) have one atom of rare earth samarium and five atoms of cobalt. By weight this samarium cobalt magnet alloy will typically contain 36% samarium with the balance cobalt. The energy products of these samarium cobalt alloys range from 16 MGOe to 26MGOe. These samarium cobalt magnets generally have a reversible temperature coefficient of 0.05%°C. Saturation magnetization can be achieved with a moderate magnetizing field. This series of samarium cobalt magnet is easier to calibrate to specific magnetic field than the SmCo 2-17 series magnets. In the presence of a moderately strong magnetic field, unmagnetized magnets of this series will try to align its orientation axis to the magnetic field.
