INVENTION: PRECISION RESISTORS USING AMORPHOUS ALLOYS INVENTOR: GERALD R. BRETTS ABSTRACT OF THE DISCLOSURE Precision resistors are disclosed which utilize as re- sistant elements amorphous metal alloys having the composition MaXb, where M is at least one of the elements selected from the group consisting of iron, nickel, cobalt, chromium and vanadium, X is at least one of the elements selected from the group consisting of phosphorus and boron, "a" ranges from about 75 to 85 atom percent and "b" ranges from about 15 to 25 atom percent. Compared with polycrystalline metal alloys, amorphous metal alloys evidence a superior resistivity, are mechanically stronger and show a higher thermal stability of resistance.
