These sintered magnets are also produced by a powder metallurgy
process and provide an exceptionally high energy product and resistance to demagnetisation. They are normally supplied in a magnetised
condition. Being very brittle, they must be handled with extreme care. Highly resistant to corrosion, they also have higher working temperatures than Neodymium-Iron-Boron; maximum for SmCo (1:5) is 250ºC, and for SmCo (2:17) is 300ºC.
