New Brazing Filler Metal for Heat Exchanger and High-Temperature Automotive Applications
Madison Heights, Michigan - Wall Colmonoy has introduced a new brazing filler metal for plate-and-fin heat exchangers and automotive components such as exhaust gas re-circulating systems (EGRs), radiators, and catalytic convectors.
The material, called Nicrobraz® 31, is a nickel-base high-chromium, oxidation-resistant braze filler metal. It has been demonstrated to have excellent capillary flow characteristics, a relatively low braze temperature, excellent joint strength/ductility and a low susceptibility to oxidation.
In the manufacture of plate-and-fin type of heat exchangers, Nicrobraz 31 has exceeded the strength of common brazing filler metals including those which meet AWS BNi-2 (AMS 4777), and AWS BNi-5 (AMS 4782) specifications. Burst strengths in excess of 2000 psi are consistently obtained using Nicrobraz 31 braze filler metal.
Nicrobraz 31 has a brazing range of 1095° to 1205°C (2000° to 2200°F). It is available as a powder or premixed as a paste suspension for application with the Nicrobraz "S" dispensing system. Upon request, it can also be provided as transfer tape, sheet and flux powder paste.
Wall Colmonoy Corporation manufactures nickel-base hard-surfacing alloys and brazing filler metals, and operates five contract processing facilities across the U.S. and Europe. Headquartered in Madison Heights, Michigan, Wall Colmonoy has worldwide distribution and affiliates in Canada, the U.K. and France.
