Product description

Cu Tungsten Carbide Composite Brazing Rods
Overview:
Cu Tungsten Carbide Composite Brazing Rods
Also named coper welding rods, tungsten carbide copper Brazing Rod
Tungsten copper brazing rod is also calld YD tungsten carbide composite brazing rod, composite rods, which is composed of matrix alloy and tungsten carbide grits. Surface is coated with a special flux and colored to identify the particle size of sintered hard alloy and grade.
It is a high abrasion resistant hardfacing consumable applied to the severe abrasion and cuting tools in oil drilling, earth excavating and coal mining industries.

 

Characteristics:
1. The granular hard alloy is sintered tungsten carbide with hardnes HRA89-91.
2. The matrix is so called Ni-Ag alloy with tension strength 87kg/mm2 and hardness HV265 at drawing condition, and tension strength 47 Kg/mm2 and hardness HV130 at casting.
3. The matrix and granular tungsten carbide hard alloy has micro melted that makes them to have a good jointing.
