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.
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 brazing filler metals of choice. Read about Nicrobraz® and EGRs in Nicrobraz News Issue.
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 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.
Many customers have specific brazing applications that require customized brazing alloys and brazing products in order to achieve required joining properties. Wall Colmonoy’s expert technical team and state-of-the-art manufacturing facilities are able to customize brazing products for your specific application.
Brazing Powder: Atomized in -106 and -45μm (-140and -325 mesh size). Other mesh sizes can be custom-made.
Brazing Rods: Available in diameters of 0.8, 1.6, and 3.2 mm (1/32”, 1/16”, and 1/18”) for torch brazing.
Brazing Pastes for Dispensing, Brazing Pastes for Screen Printing, Brazing Pastes for Roller Coating: Nicrobraz ‘S’ brazing filler metals are filler metal powders mixed with gel binder and packaged in 100, 225 and 550 g plastic cartridges and 3 kg jars.
Brazing Transfer Tape & Sheet: Nicrobraz® filler metal powder mixed with binder and mounted on a plastic sheet in precise thicknesses, with self- adhesive backing (transfer tape), or without (sheet).
We offer brazing courses at our renowned Modern Furnace Brazing School under the leadership of our expert brazing engineers.
For the latest in Nicrobraz® brazing products, applications, tips, techniques.
The NicroSpray™ system is specifically developed for applying Nicrobraz® brazing powders or any free flowing brazing powdered material which requires a liquid binder for adherence to a workpiece – evenly, quickly and smoothly.
Our manufacturing facilities in North America and Europe are equipped with modern laboratory and testing facilities. Our products are manufactured to quality standards set by international and national industrial associations. We maintain the quality assurance of ISO 9001.
Wall Colmonoy also custom formulates powder particle distribution size and chemical analysis of these products to suit specific requirements.
