Tungsten carbide burr is used widely in the shipping construction, auto engine porting and foundry fabrication. With its high rotating speed and hardness, it can machine a lot of different materials like cast iron, carbon steel, alloy steel and nonferrous material. The high life service of the product is warranted for virgin and excellent raw material which is one of the most critical factors to the tools' life.
1.Good tungsten carbide raw materials powder;
2. High performace of steel shank (GN steel) and good rust-proof property of whole burr;
Our case testing of our new burrs compared with normal burrs keep in water for same long time,
testing results as belowing:
3. Silver welding making stable quality and good wear resistance, long life time.
why use silver welding not cooper welding and what are the advantages of our silver welding :
Reason: copper welding should process at a temperature which is at least 1200 degree centigrades, but tungsten carbide which composited of WC and Cobalt often sinter at 800-1000 degree centigrades, if temperature is too high, the cobalt will turn on liquid phase which will affect the performance of carbide. then burrs will easily break and worn out.
but silver welding not only can avoid those problems, also it can improve the concentricity when welding the carbide burr with steel shank.
Our types and sizes:
All materials are tested in terms of hardness , density and T.R.S before using.
