Max Working Temp: 300°C
Used: hybrids motors or generator
Samarium Cobalt magnet have the best Br temperature coefficient (-0,035%/°C) granting the absolute higher available induction above 150°C working temperature. Despite a higher cost than other magnetic materials, SmCo magnet provides an outstanding combination of high energy, thermal stability and corrosion resistance. Protective coatings are generally not required except for particular applications.
The typical final shapes such as blocks, cylinders, rings and arcs are obtained by cutting and grinding processes of pressed standard blocks or unitary compression pre-moulded part. Extremely fine tolerances can be obtained although, because of its high brittleness, it has to be handled and assembled with care to avoid chips and cracks.
