Sintered Samarium Cobalt magnets offer very high properties, especially in thermal stability and excellent corrosion resistance.

There are two types : Sm1Co5 and Sm2Co17. Sm2Co17 with higher iHc values, offer greater stability than Sm1Co5.

-v - Sintering and plastic forming after mixing Samarium & Cobalt
-v - High Price comparing as Nd-Fe-B
-v - High Curie Point & Stable in high temperature
-v - Curie point : 700 ~ 800
-v - Using Temperature : 350
-v - Magnetic Property
......Residual Flux Density (Br) : 9.2 ~ 11.2 (KG)
......Coercive Force (Hc) : 5.5 ~ 12.2 (KOe)
......Maximum Energy ((BH)max) : 22 ~ 26 MGOe
......Density (g/) : 7.82
