Difference in Temperature Resistance
The maximum temperature resistance of neodymium-iron-boron magnets is 220 degrees Celsius, while that of samarium-cobalt magnets can reach up to 350 degrees Celsius, which is significantly higher.
Difference in Processing Characteristics
Both materials are relatively brittle. However, relatively speaking, neodymium-iron-boron magnets are easier to undergo mechanical processing.
Difference in Outer Surface
Samarium-cobalt magnets usually don't require surface treatment. But if they are used in harsh environments, their service life will be longer and they will look more attractive after electroplating. Neodymium-iron-boron magnets are prone to oxidation and thus need surface electroplating treatment.
Difference in Maximum Energy Product
The maximum energy product of neodymium-iron-boron magnets is 52 M, while that of samarium-cobalt magnets is 32 M. From this, it can also be seen that the magnetic force of neodymium-iron-boron magnets is much stronger than that of samarium-cobalt magnets.
Difference in Magnetism
When choosing a certain type of magnet, most factors are related to magnetism. Among them, neodymium-iron-boron magnets have stronger magnetism.
