Tungsten Carbide Buttons
The tungsten carbide button is sintered by coarse grained powder, with properties of high hardness and good transverse-rupture strength, as well as corrosion resistance, resistance to alkali.
Our durable carbide buttons 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 buttons are made from virgin raw materials and HIP sintered for the top good quality and high performance. There are various sizes and styles are available here and we can also make the buttons in any new design to meet our customers' requirement.
