What are the magnetic properties of aluminum, nickel, cobalt, ferrite and neodymium iron boron materials?
Ferrite: cheap, antioxidant, but low in magnetismNdFeB: known as the "magnetic king", it has excellent magnetic properties, but Curie has a low temperature and a lower operating temperature of 200 degrees and is liable to corrode
Aluminum nickel cobalt: strategic resources cobalt and nickel, so the price is expensive, magnetic properties higher than ferrite, lower than sintered NdFeB, but Curie temperature is high, so can be used for NdFeB can not be qualified in the field of high temperature
Roughly speaking:NdFeB magnetic strong, but the price is too high, the drawback is easy to oxidation and temperature resistance is not very goodFerrite: stability is very good, cheap, that is, magnetic is not very strongAluminum nickel cobalt: magnetic general, the price is relatively common, mainly for instrumentation, better temperature performance reasons.Not easily broken, teaching aids are also widely used
