INTRODUCTION:
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, Carbide picks

Production and test of tungsten carbide buttons:
1)The powder of the carbide will be prepared as the customer’s
requirement with our wet-grinding machine and spry machine.
2) Before mass production, we 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 semifinished inspection.
4) Sintering blanks to finish (HIP) and finished product's
inspection to ensure the best quality and production capacity.
