Production Description:
Cemented Carbide Buttons
This carbide button is made from coarse-grained cemented carbide,
with properties of high hardness and good transverse-rupture
strength, as well as corrosion resistance, resistance to acid and alkali, long service life.
The carbide is mainly classified by applications below:
applied for cold pavement milling-planing machine;
applied for rotary digging machinery;
applied for coal digging machine;
applied for roadway and tunnel boring machine;
and used for trench excavator, etc.
It is always widely used for crushing or milling rocks.
