ø16-22mm Cemented Carbide Buttons Low Air Pressure Hard Rock Drilling Water Well Minerals Exploration
Features:
The buttons are made of JK10.2 Grade of carbide.
The main application scenarios are of quarrying, excavating, water well drilling.
Oil & gas industry is another domain of these buttons' application, such as Tricone Bits, percussion Bits, etc.
All the buttons made of 100% virgin materials - powder of tungsten carbide and cobalt.
The average grain size is between 1.6 to 2.0 um, with hardness ranging from 89.5 to 90.5 HRA.
Divided by the shapes of the crown of the buttons, there are ball-shaped buttons and parabolic shaped buttons.
The former is good at compressive strength and high impact strength, are usually used in hard rock formations.
The latter has high excavation efficiency, are usually used in medium hard conditions.
The main physical properties are as follows:
| Grade | Cobalt | Coercivity | Density | Hardness | TRS | Grain Size |
| JK10.2 | 5.2-6.0 | 11.2-13.0 | 14.86-15.05 | 89.5-90.5 | 2750-2850 | 1.6-2.0 |
Products:
