Abstract
A magnetic metallic glass alloy exhibits, in combination, high saturation induction and high Curie temperature. The alloy has a composition described by the formula Fe.sub.a Co.sub.b Ni.sub.c B.sub.d Si.sub.e C.sub.f, where 'a'-'f' are in atom percent, 'a' ranges from about 75 to about 81, 'b' ranges from 0 to about 6, 'c' ranges from about 2 to about 6, 'd' ranges from about 11 to about 16, 'e' ranges from 0 to about 4, and 'f' ranges from 0 to about 4, with the provisos that (i) the sum of 'b' and 'c' may not be greater than about 8, (ii) 'd' may not be greater than about 14 when 'b' is zero (iii) 'e' may be zero only when 'b' is greater than zero, and (iv) 'f' is zero when 'e' is zero. This alloy is suitable for use in large magnetic cores used in various applications requiring high magnetization rates, and in the cores of line frequency power distribution transformers, airborne transformers, current transformers, ground fault interrupters, switch-mode power supplies, and the like.
