Abstract

A process is disclosed for making fine metallic fibers comprising forming a continuous tube about a plurality of coated metallic wires for providing a first cladding. The first cladding is drawn for reducing the outer diameter and for diffusion welding the coating within the cladding. The tube is mechanically removed to provide a first remainder. The first remainder is drawn for reducing the diameter thereof to transform the plurality of metallic wires into a plurality of fine metallic fibers. In one example, the diffusion welded coating is removed for providing the plurality of fine metallic fibers. In another example, a plurality of the first remainders are assembled and a continuous tube is formed about a the first remainders for providing a second cladding. The second cladding is drawn for reducing the outer diameter. The tube is mechanically removed to provide a second remainder. The second remainder is drawn for reducing the diameter thereof to transform the plurality of fine metallic fibers into a plurality of ultra fine metallic fibers. The diffusion welded coating is removed for providing the plurality of ultra fine metallic fibers.
