ABSTRACT:
An amorphous Co-based metal filament having a circular cross-section made of an alloy composed mainly of Co-Si-B or Co-Me-Si-B (wherein Me is at least one metal selected from the group consisting of Fe, Ni, Cr, Ta, Nb, V, Mo, Mn, W and Zr). This filament is produced by jetting the above alloy into a rotating member containing therein a cooling liquid through a spinning nozzle having a hole diameter which is determined according to the amorphous metal-forming ability (critical thickness to form an amorphous phase) to thereby cool-solidify the jetted molten alloy and form a filament, and then winding the filament continuously on the inner walls of the rotating member by the rotary centrifugal force thereof. This amorphous metal filament is corrosion resistant, is tough and has high electromagnetic characteristics, and is very useful as industrial materials, such as electric and electronic parts, composite materials and fibrous materials.
