ABSTRACT:
A rectangular hysteresis magnetic alloy consisting of 0.5-10 wt. % of Nb the balance of Fe and a rectangular hysteresis magnetic alloy consisting of 0.5-10 wt. % of Nb, 0.01-60 wt. % in total amount of at least one element selected from the group consisting of 0-10% of V, 0-25% of Ta, 0-25% of Cr, 0-20% of Mo, 0-10% of W, 0-30% of Ni, 0-20% of Cu, 0-45% of Co, 0-5% of Ti, 0-5% of Zr, 0-5% of Si, 0-5% of Al, 0-5% of Ge, 0-5% of Sn, 0-5% of Sb, 0-3% of Be, 0-15% of Mn, 0-2% of Ce and 0-1.5% of C, and the balance of Fe have an excellent rectangular hysteresis loop, a coercive force of more than 2 oersteds, excellent forgeability and workability and are particularly suitable as a magnetic material for electromagnetic devices requiring rectangular hysteresis loop.
