Macro Tungsten Carbide Powders(MTC,Macro WC,Cystalline WC)
Macro Tungsten Carbide Powder As Hard Phase Of Matrix Powder And PTA Powder
Product Introduction:
Macro Tungsten Carbides (MTC) are fully carburized, mono tungsten carbides (WC)
that are stoichio-metric compounds with a consistent carbon content of approximately 6.1 wt. %.
MTC particles are considerably more thermodynamically stable than fused tungsten carbides
as a result of their specific composition and microstructure.
MTC materials are designed to be the hard phase constituent of a wear-resistant surface.
Depending on the surfacing process, they can be blended with self-fluxing alloys
or used a filler material for rods, electrodes or infiltration applications.
Overlays containing these materials offer strong abrasive wear resistance and moderate impact resistance.
MTC products are appropriate for many different applications with different wear
conditions by the process of oxy-acetylene welding, laser cladding,PTA,Arc Welding.
