A process for making fine and ultra-fine metallic fibers is disclosed comprising arranging a multiplicity of metallic wires to form an assembly of the metallic wires. The assembly of the metallic wires is wrapped with a wrapping material to form a wrapped assembly. A plurality of the wrapped assemblies are inserted into a tube for providing a cladding. The cladding is drawn for reducing the outer diameter thereof and for reducing the cross-section of each of the multiplicity of metallic wires within the cladding to transform the multiplicity of metallic wires into a multiplicity of fine or ultra-fine metallic fibers. The cladding is removed for providing the multiplicity of fine or ultra-fine metallic fibers. In one example, the metallic wires are coated with a coating material formed from the same material as the wrapping material and the cladding material.
