Amorphous alloys have attractive properties which make possible their use as cores for transformers, these properties being a low watt loss, which is due to an inherently low magnetic anisotropy, and a high resistivity. However, one of the most serious disadvantages of amorphous alloys is the low thermal stability of the magnetic properties and the fact that their magnetic properties, such as saturation flux density (Bs), decrease at the temperature of the energized or excited core. In order to eliminate the disadvantages of the known amorphous alloys, the present invention proposes an amorphous alloy having a composition of Fe74-80 Si8-19 B6-13 C0-3.5. This alloy is specifically adapted so that it can be used as a transformer core which can be energized or excited at a high flux density. |
