| Grade | Density (g/cm³) | Hardness (HRA) | T·R·S (N/mm2) | Application |
| YG4C | 15.0 | 89.5 | 1800 | Maily used as small buttons for percussion bits and as the inserts of rotary prospecting bits to cut soft, medium-hard formations. |
| YG6 | 15.8 | 89.5 | 1700 | Maily used as the buttons of small and mediumsized percussion bits and as the inserts of rotary prospecting bits to cut soft, medium-hard formations. |
| YG8 | 14.7 | 88.5 | 2300 | Maily used as the buttons of small and mediumsized percussion bits and as the inserts of rotary prospecting bits to cut soft,medium-hard formations. |
| YG8C | 14.7 | 88.0 | 2300 | Maily used as the buttons of small and mediumsized percussion bits and as the inserts of rotary prospecting bits to cut soft, medium-hard formations. |
| YG9C | 14.5 | 87.0 | 2400 | Maily used as the inserts and buttons for rotary percussive bits, coal-cutting bits and tricone bits to cut medium-hard and hard formations. |
| YG11C | 14.4 | 86.5 | 2450 | Chiefly for the inserts and buttons of heavy rock drill bits and rotary-percussive bits, coal-cutting bits and tricone bits to cut medium-hard and hard formations. |
| YG13C | 14.3 | 86.0 | 2500 | Mainly used as the inserts and buttons of tricone bits rotary-percussive bits and heavy rock drill bits to cut medium-hard and hard formations. |
| YG15 | 14.0 | 86.5 | 2500 | It is stronger, and is mainly used as the inserts and buttons of rotary-percussive bits, heavy rock drill bits to cut hard and very hard formations. |
| YG16 | 14.1-14.3 | 87.5 | 2400 | It is mainly used for making cemented carbide substrate tips to be used in PDC cutters for excavating coal and oil field PDC bits. |
| YG20 | 13.4-13.7 | 85.0 | 2254 | Mainly for the stamping dies used in the conditions of heavy impact load and large strees. |
-Features of tungsten carbide drill bit buttons
1.Using over 99.95% high purity tungsten carbide powder, it has a better strength and hardness combined with a longer service life than the normal one.
2.Taking isostatic pressing machine, our drill bit button has a
uniform density and do not break easily.
3.Sintered by overvoltage sintering fuenance, the abrasive
resistancing of carbide button can be increased by 24%.
4.Grinted by centerless grinder, it has precis measurement.Be
welted tightly, it do not drop from drill.
