ABSTRACT:
Method of making copper clad conductor by impinging of copper particles upon a heated steel wire to cause adhesion of the particles to the wire, by coalescence, building up the particles to form a coating and then drawing the coated wire to the required diameter. The coated wire may be heat treated to cause flow of copper to improve the surface finish before the drawing process. The copper particles may be directed at the wire by a spraying technique. Alternatively, the wire is passed over a fluidized bed of the particles and through a cloud of particles thrown up by the bed.
