Tungsten Carbide (WC) Powder: New product

Tungsten carbide is a fine grey powder containing equal parts of Tungsten (W) and Carbon (C). Molar mass of WC is 195.85 gmol-1. Tungsten carbide is approximately two times stiffer and denser than steel. Young modulus of tungsten carbide is approximately 530-700 GPa and is comparable with hardness of corundum (∝-Al2O3).

Physical and chemical properties

Tungsten carbide has high melting point at 2870 ºC and boiling point of 6000 ºC under atmosphere pressure (1 atm). Thermal conductivity is 110 Wm-1K-1 and the thermal expansion coefficient of 5.5 μmm-1K-1.

WC starts to oxidize at 500-600 ºC. It is resistant to acids and is only attacked by hydrofluoric acid/nitric acid(HF/HNO3) mixture above room temperature. It is unreactive to dry H2 up to its melting point. It reacts with fluorine (F2) gas at room temperature and chlorine (Cl2) gas above 400 ºC. At high temperatures and pressures WC reacts with aqueous sodium carbonate (NaCO3) forming sodium tungstate (Na2WO4).

Applications

Tungsten carbide is used for making

  • Cutting tools for machining
  • Surgical instruments
  • Jewellery
  • Mining tools
  • Sports equipment

FLEW Tungsten Carbide powders

We sell crushed cast tungsten carbide powder with the particle size range from 100 μm – 350 μm. We provide exactly quality control powders with high purity and uniform batches.

Why and How we do quality control?

Our quality assurance process ensures our customers getting high quality powders with higher packing density.

We do sampling using Rotary splitting (riffling) machine for each incoming batch for quality control tests. We check each batch for

  • Purity and crystallinity by X-ray Diffraction (XRD)
  • Particle shape, size and size distribution by Optical microscope analysis
  • Loose fill/packing density

We would also be able to provide high resolution particle morphology by Scanning Electron Microscopy (SEM) as well as trace elemental analysis either by Energy-dispersive X-ray spectroscopy (EDX) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) according to customer’s need.
