PURPOSE: To permit the manufacture of a magnetic product combining high saturation magnetic flux density and high megnatic permeability and provided with high mechanical properties and heat stability and thus to easily obtain a megnetic product of high performance even with a complicated shape in a magnetic head core, a transformer, a choke coil or the like.
CONSTITUTION: This is high saturation megnetic flux density ferrous alloy powder and ferrous soft magnetic alloy powder having a compsn. shown by the following formulas 1, 2, 3 and 4, i.e., (formula 1):(Fe1-a Coa)b BX Ty T'z (formula 2): Fe b Bx Ty T'z, (formula 3):(Fe1-a Coa)b Bx Ty and (formula 4): Fe b Bx Ty; where in the above each formula, T denotes one or ≥ two kinds of elements selected from a group constituted of Ti, Zr, Hf, V, Nb, Ta, Mo and W and furthermore contains either Zr or Hf or both, and T1 denotes one or ≥ two kinds of elements selected from a group constituted of Cu, Ag, Au, Ni, Pd and Pt as well as, by atomic%, a≤0.05, b≤92, x=0.5 to 16, y=4 to 10 amd z≤4.5 are satisfied.
