JK20.2 Tungsten Carbide Buttons 89.5HRA Carbide Mining Buttons For Gas Industry
High-Performance Tungsten Carbide Button Tungsten Carbide Button Mining Button
Description:
The carbide buttons are sintered by coarse-grained cemented carbide, with the properties of high hardness and good transverse-rupture strength, corrosion resistance, resistance to acid and alkali, long service life, etc.
*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.
Specification
Mining tools include rock drill, buttons, coal cutting bits, for mining tools

Production and test of tungsten carbide buttons:
1) Carbide Buttons will start to prepare the powder as the customer’s requirement with our wet-grinding machine and spry 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) Sintering blanks to finish (HIP) and finished products inspection to ensure the best quality and production capacity.
