Tungsten Carbide Material Properties
Hard and rigid yet has very high impact resistance and high strength and higher compressive strength than all known melted, cast and forged metals and alloys. Resistance to deformation and deflection is high. Resistant to heat and oxidation with low temperature resistance. Dimensional stability with no heat treating required. While there are many different grades of tungsten carbide, these basic properties apply to all grades.
Specific grades achieve corrosion-wear resistance that approaches that of noble metals.
Applications: wide variety of applications from numerous carbide grades for high speed cutting tools, wear resistant material
