Samarium Cobalt Disc Magnets
Samarium cobalt (SmCo) disc magnets are strong permanent magnets that perform well in high or very low temperature environments. Part of the rare earth magnet family, SmCo magnets have a high resistance to corrosion or demagnetization. Because of their superior magnetic properties, our SmCo magnets are ideal for applications where high-temperature performance is critical, space is a limiting factor and high-magnetic strength is required.
Please note that special safety precautions should be taken when handling & packaging this material.

SmCo Disc Magnet Applications
Samarium Cobalt (SmCo) magnets have excellent temperature stability while maintaining their magnetic properties in extreme temperature conditions. They are well suited for technical applications where high-performance and magnetic strength is required in very low or high temperatures. SmCo magnets are widely used in the automotive, aerospace, medical, military, industrial manufacturing, semiconductor, wind, power, oil and energy industry. (top)
Common applications for SmCo magnets include:
SmCo Magnet Approximate Pull Info
The approximate pull info listed for SmCo disc magnets are for reference only. These values are calculated under the assumption that the magnet will be attached to a flat, ground 1/2" thick mild steel plate. coatings, rust, rough surfaces, and certain environmental conditions can significantly reduce the pull force. Please be sure to test the actual pull in your actual application. For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure. (top)
Safety Precautions for Samarium Cobalt Magnets
SmCo magnets are hard, very brittle and high in magnetic strength. They can also snap together with great force, and chip or break if dropped or snapped together. Therefore, they require careful handling and packing in order to prevent injuries or damages to the magnets. (top)
