Abstract

The present invention relates to a wear-resistant high permeability alloy nsisting of Ni, Nb, C and Fe, a wear-resistant high permeability alloy consisting of Ni, Nb, C and Fe as main components and at least one element selected from the group consisting of Cr, Mo, Ge, Au, Co, V, W, Cu, Ta, Mn, Al, Si, Ti, Zr, Hf, Sn, Sb, Ga, In, Tl, Zn, Cd, rare earth element, platinum element, Be, Ag, Sr, B, P, N, O, S as a secondary component and a method of manufacturing the same and a magnetic recording and reproducing head, and an object of the invention is to obtain an excellent wear-resistant magnetic alloy having easy forging processability, a large effective permeability, a saturated flux density of more than 4000G, and a recrystallization texture of {110}<112>+{311}<112>+{111}<112>, and a wear-resistant high permeability alloy consisting by weight of Ni 60-90%, Nb 0.5-14%, C 0.0003-0.7% and the remainder Fe and a small amount of impurities, and having a recrystallization texture of {110}<112>+{311}<112>+{111}<112> with an effective permeability of more than 3000 at 1 KHz and a saturated flux density of more than 4000G.
