Process of making fine and ultra fine metallic fibers

A process for making fine metallic fibers comprising:

• coating a plurality of metallic wires with a coating material;
• forming the plurality of metallic wires into an assembly of metallic wires;
• encasing the assembly of metallic wires with a wrapping material for providing a bound assembly;
• forming a continuous tube about the bound assembly for providing a cladding;
• drawing the cladding for reducing the outer diameter thereof and for reducing the cross-section of each of the plurality of metallic wires within the cladding and for diffusion welding the coating material and the wrapping material within the cladding to form a substantially unitary coating material with the plurality of metallic wires contained therein;
• mechanically removing the tube to provide a remainder comprising the diffusion welded coating material and the wrapping material with the plurality of metallic wires contained therein;
• drawing the remainder for reducing the diameter thereof and for reducing the corresponding cross-section of each of the plurality of metallic wires contained therein to transform the plurality of metallic wires into a plurality of fine metallic fibers;
• and
• removing the diffusion welded coating material and the wrapping material from the remainder for providing the plurality of fine metallic fibers.

A process for making ultra fine metallic fibers comprising:

• coating a plurality of metallic wires with a coating material;
• forming a continuous tube about the plurality of metallic wires for providing a first:
• cladding;
• drawing the first cladding for reducing the outer diameter thereof and for reducing the cross-section of each of the plurality of metallic wires within the first cladding and for diffusion welding the coating material within the first cladding to form a substantially unitary coating material with the plurality of metallic wires contained therein;
• mechanically removing the tube to provide a first remainder comprising the diffusion welded coating material with the plurality of metallic wires contained therein;
• drawing the first remainder for reducing the diameter thereof and for reducing the corresponding cross-section of each of the plurality of metallic wires contained therein to transform the plurality of metallic wires into a plurality of fine metallic fibers;
• assembling a plurality of the drawn first remainders;
• forming a continuous tube about the assembly of drawn first remainders for providing a second cladding;
• drawing the second cladding for reducing the outer diameter thereof and for reducing the cross-section of each of the plurality of fine metallic fibers within the second cladding and for diffusion welding the coating material within the second cladding to form a substantially unitary coating material with the plurality of fine metallic fibers contained therein;
• mechanically removing the tube to provide a second remainder comprising the diffusion welded coating material with the plurality of fine metallic fibers contained therein;
• drawing the second remainder for reducing the diameter thereof and for reducing the corresponding cross-section of each of the plurality of fine metallic fibers contained therein to transform the plurality of fine metallic fibers into a plurality of ultra fine metallic fibers;
• and
• removing the diffusion welded coating material from the second remainder for providing the plurality of ultra fine metallic fibers.
