When deciding between Neodymium Magnets and Samarium-Cobalt Magnets, there are key differences to consider before you make your decision. Some of the main difference between the two types of rare earth magnets are:
ADVANTAGES OF EACH TYPE OF RARE EARTH MAGNET
Neodymium magnets have the highest energy product of any material, and this type of magnet is known for its ability to be created in a wide range of available shapes, sizes, and grades.
Samarium-Cobalt magnets are known for their corrosion resistance and thermal stability. These characteristics make this type of magnet ideal for applications requiring resistance to wide-ranging temperatures and environments.
DISADVANTAGES OF EACH TYPE OF RARE EARTH MAGNET
Neodymium magnets are susceptible to corrosion and often require a protective coating. Magnetic Hold offers protective coating in the following materials: nickel, zinc, tin, silver, gold.
Samarium-Cobalt magnets are known for being more expensive compared to other types of magnets because of their durability in harsh, high-temperature environments.
