Tungsten carbide composite brazing rods are manufactured using premium, clean, WC-Co particles. The quality of WC-Co particles allows excellent wetting of the tungsten carbide particles during deposition, thereby virtually eliminating “ burnt” carbides and premature breakdown of the deposit. According to different working conditions, both sharp edged and blunt edged carbide are used. The former is suitable for cutting working condition, while the latter is for the mill working condition, mainly applied in the down-hole milling and fishing tools, centralizer.

Surfacing Coating/Spraying/Cladding/Overlaying Technology is one of the crucial technologies to improve the service life of the work pieces. It can be used in the form of special treatment and machining on the surface of the work pieces to improve its wear resistance against abrasion, erosion, corrosion and heat significantly and increase the service life and achieve the repair purpose finally.
