Samarium magnets are magnetic elements obtained by the combination of raw materials such as samarium and cobalt that belong to the group of rare earths, with excellent behavior against corrosion and oxidation. It also maintains a stability to the magnetic curve thanks to the high temperature of Curie. It is a material with very positive coercive values, a factor that favors the resistance to demagnetization, together with the high resistance to high temperatures (up to 350ºC) make these magnets indispensable for certain applications.
It is a material with a high hardness and should be manipulated only with tools that incorporate diamond, to cut or modify the magnet.
Like any magnet, you must first follow some production phases, before obtaining the magnetic material prepared for your application..
Samarium-cobalt magnets belong with neodymium to the rare earths magnets. There are different SmCo magnets according to the following alloy types:
SmCo 5: 36% Samarium or Sm2Co17 25% Samarium, Iron up to 18% and copper up to 12%.
Samarium-cobalt magnets resist to high temperatures but the max. operating temperature is 250°C (SmCo 5) and to 350°C (Sm2Co17). Their energy product is about 260 kJ7m³.
Samarium-cobalt magnets are quite resistant to external magnetic fields and need not be protected against corrosion.
Samarium-Cobalt magnets are a little more expensive than neodymium ones because of the rarity of the materials and because of the difficult manufacturing process. Custom Superior Powerful Samarium Cobalt Sheet Magnet
