Tungsten Carbide
[ 发表日期] 2013-6-18 [ 浏览次数] 1953

Tungsten carbide is sometimes colloquially referred to as cement carbide or simply "carbide." Its general definition is described as: Tungsten carbide is an inorganic chemical compound which contains equal numbers of tungsten and carbon atoms. It is also caled tungsten cemented carbide. Tungsten cemented carbide can be pressed and formed into shapes from fine gray powder, which is considered to be its most basic form. The applications of tungsten cemented carbide are widely reflected in industrial machinery, wear resistent tools, abrasives as well as men' s jewelry.

Chinatungsten Online of tungsten carbide manufacturer can offer different kinds of tungsten cemented carbide products based on our customers' requirements.

Tungsten cemented carbide is the preferred material for parts that must withstand all forms of wear (including sliding abrasion, erosion, corrosion/wear and metal-to-metal galling) and exhibit a high degree of toughness. It exhibits high compressive strength, resists deflection, and retains its hardness values at high temperatures, a physical property especially useful in metal-cutting applications. It provides long life in applications where other materials would not last or would fail prematurely.

Main Properties of Cement Carbide:

  • Excellent Hardness: 86~93 HRA, which equal to 68~81HRC;
  • Excellent hot working performance: Hardness could be remained at 60 HRC under 900~1000 ℃;
  • Resistance to wear: Some grades can outwear hardened steel by over 100 times
  • Resistance to corrosion: Grades with Nickel and Chromium binders are very resistant to acidic solutions
  • Impact resistance: Cemented carbides are surprisingly tough considering their high hardness.
  • High cutting speed
