1.Tungsten Carbide Composite Alloy Rod deposits an extremely durable protective coating comprising a dense mass of ultra-hard WC, embedded in a tough self fluxing Nickel alloy matrix.
2.This structure offers extremely effective protection against abrasive attack by a wide variety of hard and abrasive formations.
3.it is mainly used for surfacing welding the oil, mining, coal mining, geology, construction and other industriesin some serious wear and tear or artifacts of both cutting.Such as: milling shoes, grinding, centralizer, reamer,drill pipe joints, hydraulic cutter, scraper, plough planer knives, core bit, piling drill, twist drill, etc.

Flux Coated
FLUX Flux serves two main purposes. The first is to remove all foreign elements from the surface to be coated. The second is to prevent oxidation of the surface being coated. If an area is left unfluxed, the torch heat will rapidly oxidize the base material and prevent adhesion of the Composite Rod material to the base material.
The deposit offers a very high wear resistance. The alloy system offers a unique re-application capability where previously coated but now worn tools can easily be refurbished.Typical applications are down hole tools such as stabilizers, hole openers and reamers, gauge applications on casing mills and other milling tools.
