Wall Colmonoy is the leader in the development and production of nickel-based brazing filler metals since 1950. Bob Peaslee, Wall Colmonoy’s materials engineer, invented a new brazing technology using nickel-based filler metals and hydrogen atmosphere furnaces. The new filler metal was named Nicrobraz®. Additional accessory and equipment innovations followed the invention of Nicrobraz – including Stop-Off™, Nicrogap™ alloys and NicroSpray® System.
Wall Colmonoy continues to develop new brazing filler metals to meet the current market demands.
Wall Colmonoy is the forerunner in the development of Nicrobraz® Ni-Cr-Si-P filler metals. Nicrobraz® 31, 33 and 152 are used throughout aerospace and automotive industries in Exhaust Gas Recirculation (EGR) Coolers and Heat Exchangers. Major manufacturers of EGR Coolers have selected Nicrobraz® 31, 33 and 152 as the filler metals of choice. Read about our latest advancements in our brazing news.
We offer brazing courses at our renowned Modern Furnace Brazing School under the leadership of our expert brazing engineers.
The original nickel-based brazing filler metal, invented by Wall Colmonoy, is the most widely applied range of high-temperature nickel-based brazing alloys. Available as powder, paste and tapes and rods.
The latest in the family of Wall Colmonoy brazing filler metals, Niferobraz™ is a new range of iron-based brazing filler metals. These alloys confer excellent resistance to corrosion and temperature.
CuBraz™ is a copper-based brazing filler for furnace brazing low-carbon and high-alloy steels. It is available in powder or suspended in a gel binder packaged in disposable cartridges.
Many customers have applications which require specific brazing alloys in order to achieve required joining properties. Wall Colmonoy’s expert technical team and state-of-the-art manufacturing facilities are able to customize alloys for your specific application.
