Tungsten Carbide Buttons for Conicals Cutting Tools and Cursher
Teeth Applied in Mining and Other Domain of Industries
Features:
This type of button, usually called be Narrow Bottom (NB) buttons,
are mainly used in mining, excavating, trenching, tunnelling, and
mulching application. It has been made of coarse grain size of raw
material-mixture of tungsten and cobalt powders. The average grain
size is between 6.0 to 8.0 um, with hardness ranging from 85.3 to
86.8 HRA.
It has good compressive strength, thermal resistant, and
anti-corrosion properties. It is suited to roadway and tunnels
excavation in hard rock layers with high impact performance and
thermal fatigue resistance. The main physical properties are as
follows:
| Grade | Cobalt | Coercivity | Density | Hardness | TRS | Grain Size |
| JK20.8 | 7.5-8.5 | 3.7-4.3 | 14.60-14.75 | 85.30-86.80 | 2300-2400 | 6.0-8.0 |
