Abstract: An Fe-base, soft magnetic alloy is disclosed. The alloy has the general formula Fe 100-a-b-c-d-x-y M a M' b M" c M"' d P x Mn y where M is Co and/or Ni, M' is one or more of Zr, Nb, Cr, Mo, Hf, Sc, Ti, V, W, and Ta, M" is one or more of B, C, Si, and Al, and M'" is selected from the group consisting of Cu, Pt, Ir, Zn, Au, and Ag. The subscripts a, b, c, d, x, and y represent the atomic proportions of the elements and have the following atomic percent ranges: 0 ≤ a ≤ 10, 0 ≤ b ≤ 7, 5 ≤ c ≤ 20, 0 ≤ d ≤ 5, 0.1 ≤ x ≤ 15, and 0.1 ≤ y ≤ 5. The balance of the alloy is iron and usual impurities. Alloy powder, a magnetic article made therefrom, and an amorphous metal article made from the alloy are also disclosed.

Abstract: A soft magnetic alloy having a good combination of formability and magnetic properties is disclosed. The alloy has the formula Fe 100-a-b-c-d-e-f Si a M b L c M' d M" e R f wherein M is Cr and/or Mo; L is Co and/or Ni; M' is one or more of Al, Mn, Cu, Ge, Ga; M" is one or more of Ti, V, Hf, Nb, W; and R is one or more of B, Zr, Mg, P, Ce. The elements Si, M, L, M', M", and R have the following ranges in weight percent: Si 4-7 M 0.1-7 L 0.1-10 M' up to 7 M" up to 7 R up to 1 The balance of the alloy is iron and usual impurities. A thin-gauge article made from the alloy and a method of making the thin-gauge article are also disclosed.
