Samarium Cobalt magnets are available on request due to end-use considerations. Please contact us for supply. Samarium Cobalt, SmCo, like Neodymium, is a Rare Earth magnet. High temperature applications where high external demagnetising forces exist, such as in motors and generators, are well suited for SmCo. With temperature coefficients lower than Neodymium, SmCo offers less variation in magnetic output over larger variations in temperature. C). Above 150°C SmCo provides more field than Neodymium and has a maximum operating temperature of up to 350°C. It can also be used at cryogenic temperatures (it has been used at temperatures nearly as low as absolute zero, -273°C). SmCo offers excellent corrosion resistance to water due to little free iron being present in its structure. Care should be taken when assembling with SmCo due to its brittle nature (e.g. wear safety glasses). SmCo could break, chip, snap or possibly even shatter if mishandled. The stability and strength of field makes Samarium Cobalt a popular choice in medical, aerospace, automotive, audio, motor, generator, pump, sensor and military applications. If you cannot find the dimensions you require, please get in touch. The standard manufacturing tolerance is /- 0.1mm on all dimensions.
