Tungsten carbide has properties of high hardness and good wear resistance. There is no obvious plastic deformation at room temperature. The products have good dimensional stability and high precision machining. WC-Ni based alloys have good chemical stability, acid and alkali corrosion, thereby increasing the life of the product. As the above-mentioned characteristics of the carbide, it is widely used in the ball rolling bearing industry body, fluid sealed rotary ball valve core, oil extraction machine one-way spool valve seat, and many other military and civilian high-tech fields.
