K30Fine14.6-15.090-90.52600-2800Hight toughness, easy to be brazed without heat preservation.Suitable for rosewood, solid wood, pinewood, and other wood with a lot of stammers.
K10Ultrafine14.6-15.092.5-931800-2000High hardness, suitable for finish machining of iron, nonferrous metal, ceramic and other alloy,semi-finish machining of hardwood, chipboard, MDF and HDF. It's best to use silver soldering.
K40Coarse13.8-14.287.5-882800-3000High toughness, difficult to break tooth. It's used specially for finger jointing tools.
K40Medium14-14.285-861700-1900Mainly used for stamping molds and ceramic molds of electronic parts, corrosion-resistant instruments of petroleum machinery, non-magnetic.
K10Fine14.5913000-3200On the basis of ensuring high bending strength, the wear resistance of cemented carbide is enhanced, the cutting edge is dense and sharp, which is conducive to the flatness of processing and has good welding performance. It is used for food packaging, printing, aluminum foil,

Production technics

  • Tungsten carbide strips are mainly made from wolfram carbide and cobalt powder by powder metallurgy methods. The main production process of tungsten carbide bar stock is powder milling, ball milling, pressing and sintering. For different uses, the content of WC and Co in tungsten carbide flat bar is not the same.

 
Application

  • Tungsten carbide flat strips are mainly used in woodworking, metalworking, molds, petroleum machinery, textile tools and other industries. Tungsten carbide square bar is mainly used to process solid wood, density board, gray cast iron, non-ferrous metal materials, chilled cast iron, hardened steel, PCB, brake materials, etc. Carbide rectangular strips of suitable material should be selected according to the specific application.

 
Main Process flow

Powder milling→ formula according to application requirements → wet milling → mixing → crushing → drying → sieving → adding forming agent → redrying → sieving to obtain cemented carbide powder→ granulating → pressing → forming → low-pressure sintering →blanks→Flaw inspection→Packing→Warehousing
