Sintered SmCo magnets, i.e. Sintered samarium cobalt magnets, are those permanent magnetic materials that based on a hexagonal crystal structure (1:5 type SmCo magnets) or a rhombohedral crystal structure (2:17 type SmCo magnets), and they are manufactured through a powder metallurgy process. They contain two basic elements samarium and cobalt. The samarium element can be substituted by a portion of other rare earth elements including praseodymium (Pr), cerium (Ce), gadolinium (Gd), erbium (Er), etc. the cobalt element can be substituted by a portion of iron (Fe) element to increase the magnets’ saturation magnetization (Ms). in order to control the microstructure and the microchemistry so as to meet required performance, it is also critical to add a small portion of copper (Cu), zirconium (Zr), titanium (Ti), etc. high performance smco segment
Samarium Cobalt Industrial Permanent Magnets magnetic materials, unlike common commercial materials that have ASTM classifications, are difficult to manufacture and fabricate and present a special set of challenges. Therefore, the design team must take special care when creating a custom solution for your application. suited to the following applications:
Motorsports – Get ahead of the competition with innovative high performance materials that maximize torque and acceleration in the smallest, most reliable package.
Aerospace – Make your design smaller and lighter and eliminate water cooling with the unmatched temperature stability.
Automotive – Easier miniaturization and more powerful motors result in accelerated vehicle electrification. Samarium Cobalt Industrial Permanent Magnets
