Customized Zhuzhou Carbide Tungsten Steel Inserts with Dome Button Design - 20mm to 26.5mm Diameter, 2400-2600 MPa TRS
Precision-engineered carbide dome buttons designed to enhance drilling and excavation operations with superior performance and durability in demanding industrial applications.
Cemented carbide is a composite material manufactured through powder metallurgy, combining refractory metal hard compounds (WC, TiC) with bonding metals (Co, Ni, Fe). This results in exceptional hardness, wear resistance, strength, modulus of elasticity, low thermal expansion, high red hardness, and stable chemical properties.

- Brazing: Uses filler metal with lower melting point to bond carbide buttons to tool substrate
- Press-Fit: Precision manufacturing for tight fit into cavities using hydraulic presses
- Adhesive Bonding: Specialized adhesives create strong bonds between carbide and substrate
- Mechanical Fastening: Screws, bolts, or rivets secure buttons through pre-drilled holes
- Sintering: Direct bonding during manufacturing using heat and pressure for metallurgical bond
- Welding: Melting and solidification of materials along joint area for fused bond
Selection depends on tool type, button design, material compatibility, and required strength and durability.
Designed for complex application environments including underground coal mining with unclear geological components and high-power equipment requiring propulsion and shear force resistance. These carbide buttons provide excellent impact resistance, heat resistance, and wear resistance for demanding industrial operations.
Tungsten carbide buttons can be customized according to your technical drawings to precisely match your specific drilling tools and application requirements.
