铈钴铜铁[Ce(Co_(1-x-y)Cu_xFe_y)_5]永磁材料乃稀土永磁材料之一。其磁性能比铝镍钴和铁氧体高得多。一般B_r=6000～7000GS,H_c=4000～4500Oe,(BH)_(max)=9～12MGOe,在稀土永磁中属中等磁性能。由于它采用了廉价的铈、铜、铁代替了Sm(Pr)Co_5中的钐(镨)和部分钴,因而成本低,售价仅为Sm(Pr)Co_5的三分之一,是一种有发展前途的稀土永磁。由于此种材料的磁性能适中,价格低廉,因而已广泛应用于磁选机、磁性泵、发电机、电动机、电子钟、电子手表及各种音响
Cerium cobalt copper iron [Ce (Co_ (1-x-y) Cu_xFe_y) _5] Permanent magnet material is rare earth permanent magnet material. Its magnetic properties are much higher than Alnico and Ferrite. Generally B_r = 6000 ~ 7000GS, H_c = 4000 ~ 4500Oe, (BH) _ (max) = 9 ~ 12MGOe, in the rare earth permanent magnet medium magnetic properties. Because of its low cost of cerium, copper and iron in place of samarium (praseodymium) and part of cobalt in Sm (Pr) Co_5, its low cost and its price is only one third of that of Sm (Pr) Co_5 There are promising rare earth permanent magnet. Due to the magnetic properties of this material is moderate, the price is low, which has been widely used in magnetic separator, magnetic pumps, generators, motors, electronic clocks, electronic watches and a variety of audio
