The total carbon content of tungsten carbide in China is roughly divided into three paraffin processes. The total carbon of tungsten carbide for vacuum sintering is about 6.18±0.03% (free carbon will increase).
The total carbon content of tungsten carbide for paraffin process hydrogen sintering is 6.13±0.03 % Total carbon of tungsten carbide for hydrogen sintering in rubber process=5.90±0.03% The above processes are sometimes cross-processed.
Therefore, the determination of total carbon of tungsten carbide should be based on specific conditions.
