| 3. Applications |
|
|
| Fused Tungsten Carbide has high hardness and super abrasion resistance, which widely used for hardfacing in the following fields: |
| |
 |
Aiguilles and stabilizers in oil field |
|
Easy abrasion parts of crusher and miller
in mining and coal industry |
|
Big transmission gear wheel of large
roller and presser |
|
Parts of bulldozer and excavator in construction
industry |
|
Cutting tools in steel and sugar industry |
|
Easy abrasion machine parts for construction
materials and grain processing etc. |
