Product description
Cemented carbide seal ring is a powder metallurgy seal ring made of carbide (WC, TiC) micron-level powder of high hardness refractory metals as the main component, with cobalt (Co) or nickel (Ni), molybdenum (Mo) as the binder, pressed into a ring shape and sintered in a vacuum furnace or hydrogen reduction furnace.
The cemented carbide seal ring has a matrix consisting of two parts: one part is the hardened phase; the other part is the bonded metal.
According to the customer's different use environment to produce the corresponding grade of carbide seal ring, specifications are also available in a variety of diameters, with the seal ring series of glossy surface, abrasive surface, concave surface, convex surface grinding equipment and capabilities to provide customers with better service.
