Sintered Samarium Cobalt rare-earth (SmCo) magnets are manufactured by using powder metallurgy techniques which include stringent process controls and complicated heat treatment cycles. The composition of this alloy is approximately 35% Samarium, 60% cobalt with the balance being Fe & Cu. By varying the percentages of this composition and changing the sintering & heat treatment cycles the two grades 1:5 & 2:17 are produced. The difference between them is in energy product, temperature coefficient and magnetisation force required tosaturate. The 2:17 offers a better performance & lower temperature coefficient, however it is slightly more expensive and requires very high fields to magnetise it.
Both grades exhibit excellent energy, temperature and corrosion resistant properties and should be considered as your first choice of material when a compact high energy field is required at temperatures of over 100°C or hostile environments. Being almost impossible to de-magnetise SmCo magnets have a vast range of applications ranging from servo-motors, robotics, machine tools, to relays, sensors & UHV magnetrons.
