    Joining Parts for High-Temperature and Corrosion Applications for Aerospace, Automotive, Energy, Nuclear, and Defense industries.

    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.

    Forerunner in the development of Nicrobraz® Ni-Cr-Si-P filler metals

    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.

    Nicrobraz® 31, 33 and 152

    • Developed for use in the fabrication of modern heat exchanger systems
    • Contains optimal proportions of phosphorus and silicon
    • Enhanced corrosion resistance
    • Increased joint strength
    • Improved substrate structural integrity

    We offer brazing courses at our renowned Modern Furnace Brazing School under the leadership of our expert brazing engineers.
