Cemented Carbide Buttons (Spherical Buttons) Description:
Cemented carbide buttons (spherical buttons) of the ZK series, employed in mining and oil field drilling, exhibit exceptional overall performance with high toughness in their physical and mechanical properties. The porosity was controlled at A02B00 in the microstructure. Carbide buttons of the ZJ series, used as cap tips and spiral tips, demonstrate fatigue-free wear and outstanding impact resistance.
