Application of carbide spherical button
Tungsten Carbide spherical buttons due to its high hardness of the cemented carbide and other
characteristics are widely used in mining and quarrying and cutting
process, also may be placed in many other fields.
Production process of cemented carbide button
Firstly, we make raw material powder according to customer's
requirements.
Secondly, we press the powder to the shape and size clients
required.
Thirdly, the dies are sintered in the oven. Fourthly, some need
post-handle if customer need.
