Product Description
Spherical Tungsten Carbide Buttons Overview
Our precision-engineered spherical carbide buttons are designed for superior performance in demanding drilling and excavation operations. These high-quality tools withstand extreme conditions while delivering exceptional efficiency across various applications.
Material Composition & Properties
Cemented carbide is a composite material manufactured through powder metallurgy, combining refractory metal hard compounds (WC, TiC) with bonding metals (Co, Ni, Fe). This composition provides:
- High hardness and wear resistance
- Exceptional strength and modulus of elasticity
- Low coefficient of thermal expansion
- High red hardness capabilities
- Stable chemical properties

Applications & Performance Requirements
These spherical buttons operate in complex environments including underground coal mining with unclear geological components and high-power equipment generating propulsion and shear forces. This demands exceptional:
- Impact resistance for sudden force applications
- Heat resistance for high-temperature operations
- Wear resistance for extended service life
Industry Applications
Polyconical, parabolic, and mushroom tungsten carbide buttons are standard shapes for coal mining applications. They are suitable for:
- Welding coal mining equipment
- Coal mining machines in mid-soft rock formations
- Tunnel excavation in hard rock formations
- Drilling on extra hard rock formations
- Tunnel excavation in complicated rock formations
