1.Products description
Tungsten carbide buttons are mainly used for high and low pressure DHT drill and hydraulic Screw-in drill and so on.
They are suitable for hot insert or cold pressing bit inserting process, With some of the materials used in the welding process. These products are stable in quality,Excellent in performance, can meet or exceed the domestic advanced level.
We are developing carbide grades use in crushing and recycling industry. Tire, plastic, metals and trashes that needs to break down and recycle. Weariness, toughness and resistance to acidy working environment are essential properties. Specific develop grades working with different crushing materials improves the runtime of your equipment.
