Phildal tungsten co., limited is becoming a significant tungsten material supplier and exporter.
Character: wc and w2c eutectic structure. Because of its high melting point, high hardness, high wear ressistance, it
Applications: cast tungsten carbide is applied by oxygen-acetylene flame, arc, spray, braze and wet welding on wear places. It is also adhered firmly to the surface of wear work pieces with epoxy resin and inorganic additives at lower temperature and impact. The parts of piled-up cast tungsten carbide coating can stand high temperature and impact. It characterized by long tool life, easy mainternance, low cost and improved productivity.
