Cemented Carbide High-end Products

With the development of technology and equipments of tungsten carbide, high-end tungsten carbide products are developing to different requirements of customers. The main application of tungsten carbide products are cutting tools, mining tools and some wear parts.

1. Cutting tool

Cutting tool is one of the most significant applications of tungsten carbide, due to its high hardness, high strength, thermal stability and high precision, which dominates the world market of cutting tool gradually. At present, coated tungsten carbide CNC blade, printed circuit board (PCB) micro drill and precision hole overall tungsten carbide tool are the most high-end products in the field. So far, coated tungsten carbide CNC has diverse coating layer meets different requirements, such as aluminum oxide (Al₂O₃), titanium nitride (TiN), Hf, Zr and some rare earth elements or ceramics powder; PCB micro drills and mills focus on the coated cutting tools with less than 0.3mm diameter; precision hole overall tungsten carbide tools orient to special use and deep processing products.

2. Mining tool

Tungsten carbide has a broad prospect in energy, minerals and offshore drilling. There are three types of high-end tungsten carbide products: one is mineral mining, such as mating buttons for rock drilling; and ultra fine grain tungsten carbide drill bit for offshore drilling and deep well drilling; another one is suitable for complicate stratum cutting and public facilities construction. In a word, high-end tungsten carbide product for mining tools tends to ultra coarse grain and new structure.

3. Wear part

Some mold manufacturing industries requires high hardness, high toughness and excellent electrochemical corrosion resistance, using tungsten carbide will has better precision, strength and suitable for sealing ring bushing or wire drawing die, etc.
