SmCo Magnet

Product Specification

SmCo magnet is composed of Samarium oxide and Cobalt oxide ....rare earth elements, and manufactured by sintered process. SmCo magnets have high energy products (BHmax), and higher coercive force, higher temperature stability, better corrosion resistance, and required no special surface treatment, which are one of choices for the applications demanding under high temperature environments.
[part] SmCo magnets are made of the composition of samarium, cobalt and including other rare earth elements, by melting, pulverizing, molding and sintering process and then magnetizing the material with magnetic properties. SmCo magnets perform in high energy product and extremely low temperature coefficient, the highest working temperature can be up to 350℃, no limitation under negative temperature but when working temperature up to 180 ℃, the performance on the stability of temperature and chemistry is better than Nd-Fe-B Magnets.
Applications :
SmCo magnets are widely used in Motor, Meter, Sensor, Detector, Radar, and Aerospace/Aviation industry, Defense and Military Industry, Microwave device, Communication, Medical equipment, Instrument and various Magnetic transmission, Magnetic processor, Electric machinery, Magnetic lifter, and other hi-technology fields.
