Most distinctive features of Nd-Fe-B (neodymium-iron-boron) permanent magnets – highest values of energy force (up to 360 kilojoules/m3 and higher) and residual induction (up to 1,32 Tsl.). Density of sintered magnets is 7,4 gramms/sm3. Curie point - 420 °С .
Magnetic properties of permanent magnets are significantly higher than the ones of the ferrite & alnico magnets, while their size is smaller.
Guaranteed life performance of permanent magnets – 15 years.
