生产的PrCo5永磁体的能量最高可达26MGOe，并且具有稳定的磁性和化学稳定性。这些磁体的剩磁通常为∼10.5千克，矫顽力为4至5KoE。所实现的最大能量积仅为理论上可能的39MGOe的60%左右。低的矫顽力归因于在样品中形成的Pr5Co19或Pr2Co17杂质相，它们是氧化或对氧化效应的不完全补偿的结果。
PrCo 5 permanent magnets have been produced with energy products ranging up to 26 MGOe and which are magnetically and chemically stable. These magnets typically have remanence of ∼ 10.5 kG and a coercive force of 4 to 5 kOe. The maximum energy product achieved is only about 60% of that theoretically possible, 39 MGOe. The low coercive force is ascribed to impurity phases Pr 5 Co 19 or Pr 2 Co 17 , which are formed in the sample as a result of oxidation or of imperfect compensation for the effects of oxidation.
