Silicon carbide and tungsten carbide as mechanical seal faces/rings

2019-12-27 10:55:52

A tungsten carbide seal ring/face has a very high compressive and tensile strength,and it is very hard and has a high modulus of elasticity.Silicon carbide seal faces are even harder than tungsten carbide seal faces but are much more brittle and greater care must be taken during installation and removal. These handling difficulties have caused many users to prefer tungsten carbide in spite of the low frictional characteristics of silicon carbide.
