The experts in high-temperature brazing

    Nicrobraz, Niferobraz, CuBraz Brazing Alloys:

    Nickel, Iron and Cobalt Brazing Products for Joining of Metal Parts
    For High-temperature and Corrosion Applications

    Pioneer in High-Temperature Nickel-based Brazing

    Wall Colmonoy is the leader in the development and production of nickel-based brazing products since 1950. Bob Peaslee, Wall Colmonoy’s materials engineer, invented a new brazing technology using nickel-based filler metals and hydrogen atmosphere furnaces. Mr. Peaslee pioneered the application of hydrogen braze for aircraft turbine engine components. The nickel-based brazing product was named Nicrobraz®. Additional accessory and equipment innovations followed the invention of Nicrobraz® – including Stop-Off™Nicrogap™ alloys and NicroSpray™ System.

    Today’s Leading Experts in Manufacture and Development of Nickel-based Brazing Products

    Wall Colmonoy continues to develop new nickel-based brazing filler metals, brazing alloys and brazing products to meet the current market demands. Today, Nicrobraz®, Niferobraz™ and CuBraz™ brazing products are used in a variety of industries including aerospace, automotive, energy, nuclear and defense meeting AWS, AMS, G.E., Honeywell, Pratt & Whitney, and Rolls-Royce specifications.

    Our alloys are available as brazing powder, brazing pastes, brazing sheets, brazing tape, and brazing rods in a full range of sizes and specifications. Powders can be Gas or Water atomized and produced to specific alloy formulations. Wall Colmonoy also custom formulates brazing products to meet customer specific requirements.


    NICROBRAZ®

    NICKEL-BASED BRAZING PRODUCTS

    Wall Colmonoy is the forerunner in the manufacture and development of Nicrobraz® nickel-based brazing products.  Nicrobraz® is the original nickel-based brazing filler metal, invented by Wall Colmonoy, and the most widely applied range of high-temperature nickel-based brazing alloys. Available as brazing powder, brazing paste and brazing tapes and brazing rods.

    Nicrobraz® nickel-based brazing products are used throughout aerospace and automotive industries in Selective Catalytic Reduction (SCR) with DPF (Diesel Particulate Filler), Exhaust Gas Recirculation units (EGRs), Catalytic Converters, Fuel Cells and Heat Exchangers. Wall Colmonoy manufactures Nicrobraz® nickel-based brazing products, which are used extensively in the manufacture of these products.

    EGRs are also commonly deployed in diesel engines to reduce the concentration of NOx.  EGRs are usually brazed under high vacuum conditions using nickel-based filler metals to achieve good metallurgical bonding. Major manufacturers of EGR Coolers have selected Nicrobraz® 31, 33 and 152 as the nickel-brazing product of choice. Read about Nicrobraz® and EGRs in Nicrobraz News Issue.

    • Catalytic Convertor – Nicrobraz® 30
    • Selective Catalytic Reduction (SCR) with DPF (Diesel Particulate Filler) – Nicrobraz® 50, 30, 152
    • Exhaust Gas Recirculation units (EGRs) – Nicrobraz® 152, 31, 33

    NIFEROBRAZ™

    IRON-BASED BRAZING PRODUCTS

    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™

    COPPER-BASED BRAZING PRODUCTS

    CuBraz™ is a copper-based brazing filler for brazing product furnace brazing low-carbon and high-alloy steels. It is available in brazing powder or suspended in a gel binder packaged in disposable cartridges.
