The magnetic materials mainly magnetic materials used are ferrite, aluminum nickel and cobalt, samarium cobalt and summary. Samarium cobalt and ndfeb rare earth permanent magnet materials. The world's most used or ferrite, cheap products, followed by the summary; Aluminum nickel and cobalt and samarium cobalt temperature stability is better than ndfeb, so in some pointer instrument, military, and high-end consumer goods also cannot leave the aluminum nickel and cobalt and samarium cobalt material. The Curie temperature is 465 ℃ of ferrite, ndfeb Curie temperature is 310 ℃, aluminum nickel and cobalt Curie temperature is 800 ℃, samarium cobalt Curie temperature in 700 & ndash; — Between 800 ℃, so the temperature stability of ndfeb the worst, but the highest performance, called & other; The king of magnetic & throughout; 。 At present there are sintered and bonded magnetic material production of two kinds of process, the added adhesive binding due to the magnetic can not high, but high precision products
