Abstract
The present invention relates to a soft magnetic alloy and, more specifically, to a soft magnetic alloy used in electric transformers, pulse generators, compressions, electric chokes, energy-accumulating inductors, magnetic sensors, or the like, and a wireless power transmitting apparatus and wireless power receiving apparatus including the soft magnetic alloy.
Claims3
A soft magnetic alloy, consisting of a composition expressed by a formula:
- FeaXbYc,
- wherein X represents a first metalloid element, Y represents a second metalloid element and a content of the first and second metalloid elements (X+Y) is in the range of 9 to 15.5 at %, and
- wherein the composition consists of Fe, X, and Y,
- wherein the first metalloid element is B and the second metalloid element is Si,
- wherein a is in the range of 84.5 to 91.0 at %, b is in the range of 5.3 to 9.0 at %, and c is in the range of 3.8 to 6.5 at %, and
- wherein B/Si, which is a content ratio of B and Si, is 1.4 so that the amount of saturated magnetic induction of the soft magnetic alloy is in the range of 1.78˜1.95 T, a resistivity of the soft magnetic alloy is in the range of 45.7˜52.6μΩ·cm, and a saturated Magnetization is in the range of 182.2˜199.2 emu/g so as to be used at frequency band in the range of 110 kHz˜250 kHz.
