The invention provides a composition which is useful in applying an abrasion-resistant coating to a surface, typically by welding. The abrasion-resistant coating is preferably a mixture of tungsten carbide and an alloy. The composition is formed into a length of material extruded over a continuous metallic core, and then wound onto a spool. The composition includes both the tungsten carbide and an alloy having a melting temperature less than that of most ductile metals such as steel, alloy steel, nickel or nickel alloys. These components are mixed with an organic binder and a plasticizer. The organic binder enables the mixture to be extruded, and the plasticizer prevents the composition from becoming brittle after drying. When applied to the surface being coated, the alloy holds the particles of tungsten carbide together, and thus forms the desired coating. The alloy includes a plurality of round, or nearly round, particles. The round particles facilitate the extrusion process, and make the composition more supple. The invention also includes a method of forming the composition.
