There are a lot of introductions about samarium cobalt and neodymium iron boron magnets on the website, but they did not introduce the difference between the two. Today, I will give you a supplementary introduction, which is more detailed than the existing Baidu rankings.
One, the difference between samarium cobalt and neodymium iron boron pictures
2. The magnetic difference between samarium cobalt and neodymium iron boron magnets
Choose a certain kind of magnet, most of the factors are due to magnetism. Both of them are NdFeB Magnets stronger.
Three, the temperature difference between samarium cobalt and neodymium iron boron magnets
NdFeB can withstand temperature up to 220 degrees, and samarium cobalt up to 350 degrees, which is much higher;
4. Which is the better stability of samarium cobalt permanent magnet and neodymium iron boron permanent magnet?
NdFeB remanence temperature coefficient is relatively large, the higher the temperature rise, the lower the remanence; the samarium cobalt remanence temperature coefficient is very low, at the same temperature, the demagnetization of samarium cobalt is much less than that of NdFeB. In addition, NdFeB must be electroplated, otherwise it will easily be oxidized and corroded and weathered.
5. The price difference between samarium cobalt and neodymium iron boron
NdFeB The rare earth elements neodymium and boron account for a small proportion, so the price is relatively cheap; samarium cobalt magnets have more rare earth elements samarium and cobalt, about 70% are samarium and cobalt, so the price is relatively expensive.
Six, the difference in processing characteristics between rare earth samarium cobalt and rare earth NdFeB
Both materials are very brittle, relatively speaking, neodymium iron boron magnets are easier to machine.
Seven, the difference between the maximum energy product of samarium cobalt and neodymium iron boron
ndfeb magnet has a maximum magnetic energy product of 52M, while a samarium cobalt neodymium iron boron magnet has a maximum magnetic energy product of 32M. It can also be seen from this that the magnetic force of neodymium iron boron is much greater than that of a samarium cobalt magnet.
8. The difference between the outer surface of samarium cobalt and neodymium iron boron (neodymium magnet)
Samarium cobalt usually does not require surface treatment, but if the use environment is harsh, the service life will be longer after electroplating, and it will be more beautiful. NdFeB is easily oxidized and requires surface electroplating treatment.
