Industrial magnet is called industrial monosodium glutamate, which is widely used. Industrial magnets can be divided into: aluminum nickel cobalt magnet, ferrite magnet, samarium cobalt magnet and neodymium iron boron magnet.

Description of Industrial Magnet Characteristics Distribution
For the permanent magnets commonly used in the market, we have aggregated the following figure to compare the characteristic distribution. The higher the upper right, the higher the magnetic energy product. It can be seen that the magnetic advantages of NdFeB sintered magnets over other magnets, and the magnetic advantages of NdFeB bonded magnets over Ferrite magnets.
Description of the advantages and disadvantages of industrial magnets
NdFeB Strong Magnet has obvious performance advantages in all aspects, but the disadvantages are low temperature resistance coefficient and easy oxidation.
Ferrite Magnets are cheap and versatile, but the disadvantage is that they have a low magnetic energy product.
AlNiCo magnets has a good temperature coefficient, but the disadvantage is that it is relatively brittle and the price is not low.
Samarium Cobalt Magnets temperature coefficient and magnetic energy product are relatively balanced, but the disadvantage is high price.
Magnet users can choose suitable magnets according to their own needs and magnet characteristics.
