Sm2Co17 Hollow SmCo Magnets Extremely Strong Cobalt Samarium Magnets

Excellent performance sintered cobalt samarium magnet with high tempereture resistance


What is Smco magnet?

A samarium–cobalt (SmCo) magnet, a type of rare earth magnet, is a strong permanent magnet made of an alloy of samarium and cobalt. They were developed in the early 1970s by Albert Gale and Dilip K. Das of Raytheon Corporation.[1] They are generally ranked similarly in strength to neodymium magnets,[2] but have higher temperature ratings and higher coercivity. They are brittle, and prone to cracking and chipping. Samarium–cobalt magnets have maximum energy products (BHmax) that range from 16 megagauss-oersteds (MGOe) to 33 MGOe, that is approx. 128 kJ/m3 to 264 kJ/m3; their theoretical limit is 34 MGOe, about 272 kJ/m3. They are available in two "series", namely Series 1:5 and Series 2:17.
