Tungsten Carbide(Nickel Bonded)

Tungsten carbide is frequently employed for seal faces owing to its exceptional wear resistance, high fracture strength, superior thermal conductivity, and minimal thermal expansion coefficient. It is recognized as the premier material for enduring heat and fractures among all hard face materials. Tungsten carbide nickel bonded seal faces are widely utilized in numerous industrial applications to effectively prevent leakage between two mating surfaces.

Tungsten Carbide(Cobalt bonded)

Tungsten carbide is extensively utilized as a seal face owing to its exceptional wear resistance, high fracture strength, superior thermal conductivity, and minimal thermal expansion coefficient. It stands out as the optimal material for heat and fracture resistance among hard face materials. WC-Co bonded seal faces are prevalent in mechanical seals across diverse industrial applications, especially in pumps and rotating machinery
