Colmonoy ®

Wall Colmonoy was established 72 years ago when A.F.Wall bought the rights to an alloy “Colmonoy” which had exceptional wear and corrosion resistant properties.

The new alloys contained certain chromium boride crystals that were nearly as hard as diamonds, which provided excellent abrasion resistance.  The nickel-Chromium matrix alloy supplied the ability to survive in corrosive media.  The alloy had one more quality that was intriguing – it was self fluxing.  The boron and silicon content acted to remove surface oxides on metal surfaces to which the alloy was being applied.  This meant the base metal surface did not have to be molten to get overlays to bond.  It also meant lower application methods.

Over the years the range of alloys has been greatly extended and used across many important industries including the production of hollow-ware glass, power generation particularly in the nuclear field, as well as application in the aviation, plastic and chemicals industries.
