MAGNETICALLY HARD MATERIAL AND PRODUCT MADE THEREFROM Russian patent published in 2016 - IPC H01F1/57 H01F1/08 B22F3/12

Abstract RU 2604092 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to powder metallurgy, namely to magnetically hard material containing iron, cobalt, boron, dysprosium, copper. Wherein material also contains zirconium. Magnetic material chemical composition corresponds to formula, at. parts: (Pr_1-x1Dy_x1)_12-15(Fe_1-y1Co_y1)_rest(Zr_zCu_1-z)_y2B_6-7, where x1 = 0.44-0.48; y1 = 0.30-0.36; y2 = 1.0-2.0; z = 0.005-0.05. Product of magnetically hard material is also disclosed.

EFFECT: technical result is increase residual induction of material, while maintaining values of temperature coefficient of induction.
