Primary Material Properties
- High hardness and exceptional wear resistance
- High elastic modulus for structural integrity
- High compressive strength up to 3000 MPa
- Excellent chemical stability against acid, alkali, and high-temperature oxidation
- Low expansion coefficient with thermal and electrical conductivity similar to iron alloys
Assembly Methods
| Method | Description |
|---|---|
| Brazing | Uses filler metal with lower melting point to bond carbide buttons to tool substrate through heating process |
| Press-Fit | Precision manufacturing allows buttons to be press-fitted into cavities using hydraulic presses for secure bonding |
| Adhesive Bonding | Specialized adhesives applied to button or substrate create strong bonds after curing |
| Mechanical Fastening | Screws, bolts, or rivets secure pre-drilled carbide buttons to tool substrate |
| Sintering | Direct bonding during manufacturing using heat and pressure to create molecular-level metallurgical bonds |
| Welding | Melting carbide and/or substrate material along joint area creates fused bond upon solidification |
Applications
These tungsten carbide button bits are specifically designed for demanding industrial applications including:
- Coal mining operations
- Construction drilling projects
