Cast Tungsten Carbide:

Chemical Formula:WC/W2C


Cast Tungsten Carbide (CTC) is a so-called cast and crushed tungsten carbide.

lt is of irregular particle shape.



Adopted high temperature melting, crushing process.

Due to its high melting point, high hardness, high wear resistance
characteristics, make its have the characteristics of high temperature
resistance, abrasion resistance, impact resistant.

Products are widely used in mining, oil, metallurgical industry, steel,
construction machinery and other industries.

Such as: PDC bit, petroleum drill pipe, TC bearing, etc.


Blends of CTC with alloy powders based on Ni, Fe or Co are used to produce
superior wear protectioning coatings by PTA welding, lasercladding or other
wear protective welding applications.

Examples are conveyor screws, fan blades, wear plates. excavator bucket teeth
and crusher iaws.

Furthermore. CTC can be used for the production of drill bits.
