Brazing flux minimizes the oxidation that tends to form in the brazing process on filler metal and materials being joined. A flux formulation is most likely available for your particular metal joining project.
North America Alloy offers the following Johnson brazing flux and specialty products:
| Flux Products | Description | Temperature Range (°F) |
|---|---|---|
| Lloyd’s #7 | This general purpose flux is widely used with low temperature alloys and provides excellent results, even when diluted up to 50% with water. | 850-1650 |
| PowerBraze | An effective powdered brazing flux used on red metals and steel for low cost brazing applications. | 800-1750 |
| KwikFlux 41 | A general purpose flux used primarily with silver based alloys. Works best with torch brazing on stainless steel. | 1100-1600 |
| KwikFlux 54SB | Used on tungsten chromium carbides, high alloys and stainless oxides and has a slightly greater fluidity at low end of brazing temperatures. | 1100-1600 |
| Johnson Alum Brazing Flux | Temperature range is perfectly matched to 4047 brazing applications. Dry powder is customarily carried on a heated rod to the work piece as it nears brazing temperature. | Active above 1025 |
| Buffalo Flux 2805 CAB Flux | Controlled Atmosphere Brazing Flux for furnace applications has excellent performance from this unique SA Day Flux made at Johnson’s Buffalo Flux Facility | Meets CAB temps |
| Paste Flux | ||
| KwikFlux 54 | A general purpose paste widely used with low temperature alloys. It is extremely fluid at brazing temperatures, so it promotes good capillary flow on hard to wet materials. | 1000-1600 |
| KwikFlux 95 | Used for high temperature, prolonged, and intense heating, such as large-tipped torch brazing. Works well with AMS 4772. Flow point of 1575F | 1200-1800 |
| KwikFlux 99 | A high temperature flux for nickel-bearing brass and bronze common filler metals, high alloys, and stainless steels. Ideally suited to furnace brazing and induction brazing processes. | 1600-2200 |
| Xcel Flux SS | This paste is widely used with low temperature alloys. It is full-bodied and will produce satisfactory results, even when diluted up to 50% with water. | 780-1600 |
| KwikFlux 41B | Used on tungsten chromium carbides, high alloys and stainless oxides and has a standard open fluidity. | 1100-1700 |
| Xcel Flux NF | Used when local overheating may occur, such with induction brazing. It is a full-bodied gray flux that is formulated especially for steels at dilution of up to 50% | 1100-2200 |
| Xcel Flux NF10 | Similar to NF, but especially used when prolonged heating period is required. Increased boron additive to special formula. Affects refractory oxides formed during brazing process. | 1100-2200 |
| FloRite NF | A premixed, non-separating gray flux which requires no further dilution for general purpose brazing applications. | 1100-2000 |
| Liquid Flux | ||
| Aqui Flux | A jewelers self-pickling, water-based, hard soldering flux for all types of jeweler’s metals that is used for furnace brazing with poor atmospheres. | 1100-1500 |
| Luxi Flux | Gas corrective, alcohol-based flux for soldering or annealing all jewelers metals and used for furnace brazing with poor atmospheres. Contains Methyl Alcohol. POISONOUS, Read MSDS before using. | 1100-1500 |
| Specialty Products | ||
| Flux Remover Compound | Dry granules for mixing with water and removes flux, rust, mill & heat scale. Eliminates need for strong acids or abrasives | N/A |
| Pickling Compound | For fast pickling of gold, silver and other jewelry metals and to remove surface oxidation and scale. | N/A |
| Wax Wash | Pre-investment wax dipping solution. DO NOT USE NEAR SPARK OR OPEN FLAME! | Mix < 125, Use 140 |
