We have been in producing for the composite rods for many years. We are professional in producing the cemented carbide composite welding rods.
Our tungsten carbide only use the carbide anvil to get the pure grade YG8 tungsten carbide grits.
Then we use the good quality copper 30% or 40% to sintered them together.
Our welding rods have high wear resistance ,will increase the work life of the drilling tools and oil fishing tools. The hardness is more than 160HB..
