Hard Metal YG6 Tungsten Carbide Buttons For Rock Drilling Tool
Description:
The carbide button is sintered by coarse-grained cemented carbide, with properties of high hardness and good transverse-rupture strength, as well as corrosion resistance, resistance to acid and alkali, long service life.
They are mainly classified as follows: the cutting tips used by cold pavement milling-planing machine, the cutting tips used by rotary digging machinery, the cutting tips used by coal digging machine, the cutting tips used by roadway and tunnel boring machine, the cutting tips used by trench excavator, etc. They are widely used for crushing or milling rocks.
*Application:
It is suitable for percussion drilling, rotary prospecting bits to cut soft and medium-hard formations, and medium-hard drilling bits, also used for hardwood, non-ferrous metal, granite, and marble.
*Recommend grades for tungsten carbide buttons bits:
| Grade | Density | T.R.S | Hardness | Performance & application recommended |
| (g/cm³) | N/mm³ | (HRA) | ||
| YG4C | 15.1 | 1800 | 90.0 | Mainly used as small buttons for percussion bits to cut soft and medium hard formations. |
| YG6 | 14.9 | 2100 | 90.0 | For coring crowns, electric coal drill bits, coal cutting picks, oil cone bits and scraping knife bits, used in geological prospecting, coal mining and oil well boring. |
| YG8 | 14.7 | 2400 | 89.5 | For coring crowns, electric coal drill bits, coal cutting picks, cone drill bits and scraping knife bits, used in geological prospecting, coal mining and oil well boring. |
| YG8C | 14.8 | 2450 | 88.5 | Mostly used as the buttons of small and medium sized percussion bits and as the inserts of rotary prospecting bits to cut soft and medium hard formations. |
| YK15 | 14.6 | 2450 | 87.6 | Suitable to strips, conical buttons for rotary percussion-resistant,geological prospection buttons, cut soft and medium hard formation. |
| YK20 | 14.4 | 2500 | 86.8 | Primarily for the buttons and inserts of rotary percussion bits to cut medium-hard and very hard formations. |
| YK25 | 14.4 | 2550 | 87.2 | Primarily for the buttons and inserts of rotary percussion bits to cut medium-hard and very hard formations. |
| YG11C | 14.4 | 2700 | 86.5 | Largely for the inserts and buttons of percussion bits and tricone bits to cut medium-hard, hard and very hard formations. |

Production and test of Tungsten carbide Buttons:
1)Carbide Balls will start to prepare the powder as per the customer’s requirement
with our wet-grinding machine
2) Before mass production, we need to do a trial pressing and sintering, and we check the
appearances and the sizes of the samples with a micrometer to
ensure that the requirements of the drawings can be met before
batch production
3) Bulk production, press the raw materials to shape blanks, and
carbide tips must be passed by semi-finished inspection.
4) sinter blanks to finish (HIP) and finished products inspection
to ensure the best quality and production capacity.
