  • Fe-Si Base Alloy and Method of Making Same
    Publication number: 20210350961
    Abstract: A soft magnetic alloy having a good combination of formability and magnetic properties is disclosed. The alloy has the formula Fe100-a-b-c-d-e-fSiaMbLcM?dM?eRf 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.
