Iron-Based Brazing Filler Metals for Applications Requiring High Strength and Ductility
A range of cost effective iron-based Brazing Filler Metals, known as Niferobraz™ are available for evaluation as substitutes for nickel-based filler metals. They are available as powder, in a range of sieve sizes, or suspended in ‘S’ Binder™. Niferobraz™ filler metals, when supplied as specialized screen printing paste, produce excellent results.
Our specially formulated Niferobraz™ iron-based Brazing Filler Metals have a high chromium content, which provides excellent oxidation resistance through 1800°F (982°C)*. Niferobraz™ is used across such global industries as Automotive, Heavy Equipment, Food and Beverage, Medical Equipment, Power Engineering, Marine, Aerospace and Military.
Applications include Heat Exchangers, EGR Coolers, Catalytic Converters, Fuel Cells, Batteries, Potable Water Systems, and other assemblies that incorporate large surface areas with multiple braze joints.
*Application specific tests are recommended
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. Niferobraz™ ‘S’ brazing filler metals are filler metal powders mixed with gel binder and packaged in:
| Forms | Container Sizes | Manufactured In |
| Air applicator cartridges | 100g, 225g, and 550g (3.5 oz, 8.0 oz, and 20.0 oz) | USA and UK |
| Hand syringes made of plastic for one-time use | 100g (3.5 oz) | USA and UK |
| Bulk containers. Weights are maximum weights and can vary according to binder type. | Available on special order in 3 kg (6.61 lbs) jars for use in pressure-fed systems | USA |
| Available as tins in 1 kg (250 ml), 5 kg (1.0 L) and 20 kg (3.0 L) and buckets in 15 kg (5.0 L) and 25 kg (16.0 L) | UK |

Powder (Download Bulletin)
Niferobraz™ 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 Niferobraz™ 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.
