Wear Resistant Parts Drill Bit Inserts Cemented Tungsten Carbide Dome Buttons
Cemented Carbide Buttons Advantage
Carbide (tungsten carbide) is used in numerous industries including mining, road construction, metal tooling, machining shops, and in various pieces of equipment where a metal harder than steel is necessary. Tungsten Carbide Buttons are always mainly used for rock, geological, coal mining, and oil field.
High hardness wear Resistant tungsten cemented carbide flattop buttons for mining bits advantages are a belows:
1. Using over 99.95% high purity tungsten carbide powder,it has a better strength and hardness,thereby a longer service life.Taking isostatic pressing precision machine,our drill button has a uniform density,and do not break easily.
2. Sintered by overvoltage sintering furnace,the carbide button are 24% more abrasive resistancing.
3. Grinded by centerless grinder,its has precis measurement.It's tightly welded,do not drop from drill.
4. It is using in making down the hole drill bit,ball nose drill bit,pillar drill bit lamp.
Grade List
| Grade | Co% | Density (g/cm2) | Hardness (HRA/HV30) | TRS (N/mm2) | Application |
| XD05 | 5.5 | 14.9-15.1 | 1380-1500 | ≥2800 | High hardness and wear resistance, suitable for making various parabolic buttons. |
| XK05 | 6.0 | 14.82-14.98 | 1370-1490 | ≥2300 | Suitable for making various sizes of buttons with fine resistance to impact and wear for drilling soft and medium hard formations at a higher speed rate. |
| XD10 | 6.2 | 14.80-15.00 | 1320-1470 | ≥2000 | High toughness, suitable for making buttons for high air pressure DTH bits drilling medium hard and hard rock formations. |
| XD10B | 6.5 | 14.75-14.95 | 1300-1460 | ≥2300 | Mainly for making buttons for low air pressure bits in mining. |
| XD20C | 7.0 | 14.7-14.9 | 1320-1450 | ≥2500 | With more cobalt content and toughness than that of grade YK05, it is a tougher alternative to grade YK05 to avoid risk of breakage of bits at high speed drilling rate. |
| XK10.5 | 7.5 | 14.7-14.85 | 89.0-90.5 | ≥2600 | Mainly for making buttons for DTH bits in various sizes of conical, parabolic and spherical buttons. |
| XK10 | 8.0 | 14.6-14.76 | 1200-1320 | ≥2340 | Mainly for making buttons of medium and small sizes for bits drilling soft and medium hard rock formations, also for making inserts for other drill bits. |
| YG8C | 8.3 | 14.55-14.75 | ≥87.5 | ≥2000 | Mainly for making buttons of medium & small sizes for drilling soft and medium hard rock formations. |
