Next Generation Cladding Technology: Conforma Clad X2 

Conforma Clad X2 Logo

X2 cladding uses twin layers of Stellite™ and tungsten carbide, realizing the benefits of both materials. The Stellite under-layer offers superior corrosion protection, eliminating any access of corrosive media to the base material while the tungsten carbide top layer offers the same severe abrasive wear protection on which Conforma Clad built its reputation.
