Grade 34 SmCo magnets rank the highest performance level among commercially available SmCo magnets. With energy product up to 32-34 MGOe (255-271 kJ/m3), these high performance SmCo magnets provide more possibilities and/or solutions to smaller size, lighter weight and higher efficiency.

[1] Typical reversible temperature coefficient (RTC) of Br [α(Br)] between 20 and 150 °C (68-302 °F).
[2] Maximum operating temperature is strongly related to the load line/Pc (permeance coefficient) and operating environment of a SmCo magnet.
