Sintered ring SmCo magnet: high magnetic properties, outstanding thermal stability and high working temperature
Not a trade company, but a professional factory! We are one of few sinter SmCo magnet manufacturers in China. Last year our annual production of SmCo magnet expanded to 120 tons, which ranked Top Three in China or even in the world.
Moreover, we are accredited with TS 16949, which certify that we are qualified to manufacture SmCo magnet for the automotive industry.
Characteristics:
1. High magnetic properties: Hcj could reach up to 35KOe. (BH)max could reach high to 30MGsOe.
2. Outstanding thermal stability: For some materials, Reverse Temperature Coefficient α could reach low to -0.01% of Br/°C; Reverse Temperature Coefficient β could reach low to -0.2% of Hcj/°C.
3. High working temperature: The maximum recommended working temperature is 250C(480F) for SmCo magnet 1:5 and 350C(660F) for SmCo 2:17. The Curie Temperature could reach high to 750 C(1390F) for SmCo 1:5 and 850C(1560F) for SmCo 2:17.
4. High resistance to corrosion: No coating is needed for surface protection.

SmCo magnets is also named with SmCo magnetic steels, SmCo permanent magnets, SmCo permanent magnetic iron and rare earth cobalt permanent magnet. It is one type rare earth material permanent magnet, and It is a high performance, low temperature coefficientpermanent magnet with its high working temperature-350 degree centigrade. When working above 180 degree centigrade, its maximum energy prodcut BH and steady temperature are superior than NdFeB magnetic material. It needn't to be coated because it is difficult to be eroded and oxidized.
SmCo ring magnets widely used in transduces, instruments, etc.
