MAGNETIC MATERIAL FOR PERMANENT MAGNETS AND ITEM MADE FROM IT Russian patent published in 2016 - IPC H01F1/57 B22F3/12

Abstract RU 2578211 C1

FIELD: metallurgy.

SUBSTANCE: magnetic material containing praseodymium, iron, cobalt, boron, copper and element selected from group including gadolinium, dysprosium, samarium, cerium is suggested, it differs in that additionally contains tin. Magnetic material chemical composition complies to the equation in atomic fractions: (Pr_1-x1R_x1)_11.5-16(Fe_1-y1Co_y1)_rest(Sn_zCu_1-z)_y2B_6-20, where R is element selected from group including gadolinium, dysprosium, samarium, cerium; x1 = 0.01-0.50; y1 = 0.30-0.55; y2 = 0.5-2.0; z = 0.001-0.1.

EFFECT: magnetic material ensures increasing of the residual magnetic inductance B_Rat temperature coefficient of inductance close to zero, increased yield of finished products - ring magnets with radial texture made from the given material.
