Carbide Rolling Buttons’ Application:
Tungsten carbide buttons widely been used in mining in top hammer rock drill bits, down hole hammers, roller-cutters,long wall plough chisels, long wall shearer picks, raise boring reamers, and tunnel boring machines, used in quarrying, mining, tunneling, and civil construction industries. It is generally utilized as a button insert, mounted in a surrounding matrix of steel that forms the substance of the bit.
Tungsten carbide grade:
The components of tungsten carbide are WC(hard phase) and cobalt (binder phase).The physical properties of alloy depend on the grain size of WC and the percentage of hard phase,we have dozens of material grades for your different applications.
