Advantage
1) Made of special and excellent raw material, have more stable properties, increase the yield of complete drilling and mining bit substantially;
2) Extra grain size available, have higher impact resistance and lower hot crack and breakage;
3) Ground and tumbled, ensuring uniform of dimension and surface smoothness, easier to mount;
4) HIP sintered, increase the strength substantially therefore extend service time;
Full range of types and specifications available.

| Grade | Applications recommended |
| YG11C | Suitable for embedding rotary percussive drill bits of heavy rock drilling machines for drilling hard formations of class f=18 or above |
| YK15 | Suitable for embedding rotary percussive drill bits of light rock drilling machines for drilling medium rock formations of class f=14-15 |
| YK15.6 | Suitable for embedding rotary percussive drill bits of medium rock drilling machines for drilling medium to hard rock formations of class f=14-15 |
| YK20 | Suitable for embedding rotary percussive drill bits of medium rock drilling machine for drilling hard rock formations of class f=18 or above. |
| YK20.2 | It combines the advantages of the wear resistance of YK15.6 and toughness of YK20 with rather good stability. The product is suitable for drilling rock formations of class 15-17. |
| YK25.6 | With a unique structure, it has a higher lifetime and drilling speed. It is suitable for embedding rotary drill bits of medium drilling machines for drilling medium hard and rather hard rock formations of class f=14-16 |
