SmCo Magnets are second generation of rare earth magnets, specified into SmCo5 and Sm2Co17 . It is made of samarium, cobalt and other rare earth metal, processed through smashing, pressing and sintering. It has high energy product and extremely low temperature coefficient. Due to strong magnetic property and excellent temperature performance, its working temperature can reach 250-300°C. When working in temperature over 180°C, its energy product, temperature stability chemical stability all surpass that of neodymium magnet material. Arched Shape Rare Earth High Standard SmCo Magnet

Comparing with neodymium magnets, samarium cobalt magnets are far more appropriated to work in high temperature. Therefore, it is great for manufacturing permanent magnet motor with high performance and products used very complicated working environments. In addition, it has very strong resistance to rust, so commonly, it does not need electroplating. Customized Sintered SmCo Super Strong Magnets

Price of samarium cobalt material is higher than other material, because samarium, the main component of the material has low reserve on the earth. Arched Arciform Sintered SmCo Rare Earth Permanent Magnet

YX-18 Magnets Samarium Cobalt for Toy Structural Assembly

Composition:Samarium Cobalt Smco Magnet Sm2Co17,SmCo5
Due to its higher magnetic properties(higher Br,higher Hcj and higher (BH)max,lower temperature coefficient,higher working temperature(250-350°C) and excellent corrosion resistance,SmCo magnet is widely used in electron beam devices,high performance motors,sensors ,Generators motor,Wind power,Wind power and magnetic assemblies.It can not be replaced by other permanent magnets. Custom Shape Sintered SmCo Magnet

SmCo Material Custom Design Magnet

Samarium Cobalt (SmCo) magnets, of the Rare Earth class, have been available since the early 1970’s.
These magnets possess very high magnetic properties, excellent thermal stability, while remaining resistant to corrosion. These characteristics make SmCo magnets ideal for applications requiring a resistance to wide-ranging temperatures and environments.
SmCo magnets are manufactured by sintering or compression bonding. They are anisotropic and can only be magnetized in the direction of orientation. In general, magnetizing fields of approximately 30 to 45KOe are required to saturate SmCo magnets.
