Copper-Based Brazing Filler Metals Effective in the Brazing of Iron or Steel Assemblies
CuBraz™ is a copper Brazing Filler Metal, effective in the brazing of iron or steel assemblies in most kinds of controlled-atmosphere furnaces. CuBraz™ is an especially effective Brazing Filler Metal for joining steels, from low carbon to high alloy. With its good ability to wet iron and steel, it forms strong joints. CuBraz™ contains copper metal, rather than copper oxide, as the source of its copper content. This results in improved flow properties, fewer atmosphere problems, and the use of less material per joint. CuBraz™ has an exceptionally high, uniform metal content, which eliminates the incidence of rejects caused by variations in metal content.
CuBraz™ offers special advantages in the application stages of its use. It applies fast, permits reasonably exact control of the amount put down, adheres readily to work surfaces, and reduces waste. These advantages make it very useful for production work.
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 Pastes: Powder alloy premixed with proprietary binders to produce viscous paste suspensions. For dispensing, for Screen Printing, for Roller Coating. CuBraz™ ‘S’ brazing filler metals are filler metal powders mixed with gel binder and packaged in:

Powder (Download Bulletin)
CuBraz™ powders are stable under normal atmospheric conditions; therefore, a recommended shelf life is not given for these products. These alloy materials do not degrade, under normal storage conditions. If these materials are stored in unopened containers, and kept free from contamination, they will be usable for an indefinite period of time.
Paste (Download Bulletin)
The shelf life of CuBraz™ Brazing Paste materials is a minimum range of three to nine months (see bulletin). This means that the material will last at least that long and much longer, when properly stored in closed containers. There is no deterioration of the brazing filler metal itself. As long as the material will extrude from the cartridge satisfactorily, it is still usable.
