Advantage of tungsten carbide button
Our durable carbide with excellent fracture resistance dramatically
improve tool life with high penetration rates.
The consistent performance and tolerance are mainly attributed to
our pure raw materials and strict ISO quality control.
All of our carbide mining tips and inserts are made from virgin raw
materials
HIP sintered for the top good quality and high performance.
Various sizes and styles are available here and we can also make
the tips in any new design and sizes to meet our customers'
requirement.

Application of carbide button
Production process of cemented carbide button
The manufacturing process begins with the composition of a specific
tungsten carbide powder mixture- tailored for the application.
This powder is compacted into a form.
In a high- temperature sintering furnace, the tungsten carbide
structure of the blank is shaped at precise temperatures for
strictly defined periods.
During this heat treatment, the tungsten carbide blank undergoes
shrinkage of some 50% in volume.
The sintered tungsten carbide component gains its final finish by
additional grinding, lapping and/ or polishing processes.
