Pioneers and Today’s Leading Experts
Wall Colmonoy developed the very first heat exchanger overhaul procedure for the US Air Force. Prior to that in the 1950s, Wall Colmonoy invented Nicrobraz® nickel-based brazing filler metal and pioneered high temperature furnace brazing. Even today, Nicrobraz® is used extensively in heat exchanger manufacture and overhaul.

Wall Colmonoy Aerobraze continues to develop its brazing and manufacturing expertise resulting in increased efficiencies, significant cost savings and performance improvements.
