copper tungsten carbide composite welding rod with white flux coat
Brief Introduction
It is made of tungsten carbide particle and matrix alloy,we supply copper alloy matrix and nickel matrix alloy.
Nicke matrix alloy is with higher hardnes and better wear resistance.
Outside special flux and color is marking scrap grade,CO and WC is the main composition of sintering tungsten carbide,the hardness is HRA 89-91.This structure offers extremely effective protection against abrasive attack by a wide variety of hard and abrasive formations.
Applications
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.
