Abstract
A cemented carbide suitable as a high performance hard metal material for wire drawing of high-tensile strength alloys is provided. The cemented carbide may include a relatively low binder content with additives Cr, Ta and/or Nb to provide high wear and corrosion resistance, high thermal conductivity, high hardness and a desired hardness to fracture toughness correlation.
