About Rare Earth Magnets
Rare Earth Magnets are high strength, permanent magnets made from alloys of rare earth elements. The strongest type of permanent magnets made, rare earth magnets produce significantly stronger magnetic fields than other types of magnets, including ferrite or alnico magnets. The compounds used in the formation of rare earth magnets come from the rare earth or Lathanoid series of elements in the periodic table.
There are two types of rare earth magnets: neodymium magnets and samarium cobalt magnets. Neodymium magnets (Nd-Fe-B) are composed of neodymium, iron, boron and a few transition metals. These magnets are extremely strong for their small size, metallic in appearance. Samarium cobalt magnets (SmCo) are composed of samarium, cobalt and iron. They have good temperature stability.
Other Permanent Magnet Material
Master Magnetics also specializes in other permanent magnetic material, including ceramic and alnico. Ceramic (ferrite) magnets are composed of strontium carbonate and iron oxide. They are the least expensive material compared to alnico and rare earth magnets. Alnico magnets are made primarily from aluminum, nickel, cobalt, copper, iron and sometimes titanium. They can be either cast or sintered. Alnico magnets are very heat tolerant.
