1. Magnetic differences between samarium cobalt and neodymium iron boron magnets

Choosing a certain magnet is mostly due to magnetism. They have stronger magnetism in neodymium iron boron.

2. Difference in temperature resistance between samarium cobalt and neodymium iron boron magnets

Neodymium iron boron can withstand temperatures up to 220 degrees Celsius, while samarium cobalt can withstand temperatures up to 350 degrees Celsius, which is much higher;

3. Which is more stable, samarium cobalt permanent magnet or neodymium iron boron permanent magnet?

The temperature coefficient of neodymium iron boron remanence is relatively large, and the higher the temperature rises, the lower the remanence; The residual magnetization temperature coefficient of samarium cobalt is very low, and at the same temperature, the demagnetization of samarium cobalt is much less than that of neodymium iron boron. In addition, neodymium iron boron must be electroplated, otherwise it is prone to oxidation, corrosion, and weathering.

4. Price difference between samarium cobalt and neodymium iron boron

Neodymium iron boron rare earth elements neodymium and boron have a relatively small proportion, so their prices are relatively cheap; Samarium cobalt magnets contain more rare earth elements such as samarium and cobalt, with around 70% being samarium and cobalt, making them relatively expensive.

5. Differences in processing characteristics between rare earth samarium cobalt and rare earth neodymium iron boron

Both materials are brittle, and relatively speaking, neodymium iron boron magnets are easier to machine.

6. Difference in maximum magnetic energy product between samarium cobalt and neodymium iron boron

The maximum magnetic energy product of neodymium iron boron magnet is 52M, while the maximum magnetic energy product of samarium cobalt neodymium iron boron magnet is 32M. This also shows that the magnetic force of neodymium iron boron is much higher than that of samarium cobalt magnet.

7. Differences in the outer surface of samarium cobalt and neodymium iron boron (neodymium magnets)

Samarium cobalt usually does not require surface treatment, but if used in harsh environments, the service life after electroplating is longer and more beautiful. Neodymium iron boron is prone to oxidation and requires surface electroplating treatment.
