Abstract (en)
Vanadium-containing iron-cobalt alloy, containing a small amount of boron. An iron-cobalt alloy has the composition (by wt.) 35-55% Co, 0.5-2.5% V, 0.02 to less than 0.2% Ta + 2 x Nb, 0.0007-0.007% B, ≤ 0.05% C, balance Fe and impurities. Preferred Features: The boron content is 0.001-0.003%. The impurities comprise ≤ 0.2% Mn + Si, ≤ 0.2% Cr + Mo + Cu, ≤ 0.2% Ni and ≤ 0.005% S.
