Product Description
SmCo Block Magnets
Block Segment Magnets can be done from Materials: Sm2Co17 Magnets or SmCo5 Magnets according to customer requirement.
Becasue rare earth metal price increased crazily in the recently years, even Maximum Energy Product (BH max ) and Residual Inductance (Br ) of SmCo5 Magnets is lower than that of Sm2Co17 Magnets, the price of SmCo5 magnets maybe higher that of Sm2CO17 Magnets because SmCo5 magnets contain some rare earth metal - praseodymium(Pr).
Various Size, Uncoated or Ni coating samarium cobalt magnets if needed, Most Samarium Arc magnets are Magnetized through thickness in pairs. We would like to supply affordable price samples to customer.

FAQ What is Samarium Cobalt Magnet?
Samarium cobalt magnets or SmCO magnets is one kind of rare earth magnets made from Samarium, Cobalt, Iron, Zirconium etc which was developed in the early 1970s. There are first generation rare earth magnets-SmCo5 magnets and second generation The rare earth magnets-Sm2Co17 Magnets base on different compositions.The half finished products of Samarium cobalt magnets are made from raw materials by powder metallurgy technology, including melting ,casting, crashing, milling, pressing ,sintering, then they are made into finished products by Mag processing equipment, such Mag Spring's factory can supply the highest grade Sm2Co17 magnets in the world with the following magnetic properties: Br > 1,15 T, Hcj >2300 kA / m, Hcb > 820 kA / m , BH (max) > 250 kJ/m3.
She usually does not need coating to protect them from environment-induced corrosion because of content high percentage of cobalt metals which allows more accurate tolerances and simplifies use. Also they do not need to apply coating higher resistance temperature ratings, higher coercivity and excellent corrosion resistant. Can work for long time in high temp more than 250-350 Centigrade degree and can work more stable than Neodymium magnets.
Samarium cobalt magnets are commonly used in high performance motors, magnetic couplings, magnetic separators, sensor controls, oil pump and other equipment which performance is required to be consistent with temperature change or under easy corrosion circumstance.
