What applications and base metals is the Harris 17 Paste Brazing Flux - Eight Ounce Jar - 017FX00 suitable for?

Brazing flux is used with silver brazing alloys and some copper-phosphorus alloys when joining copper to dissimilar metals. Phos-copper alloys (BCuP series) are self-fluxing on copper-to-copper joints but still require flux when brazing copper to brass, bronze, or steel. Always use the flux recommended by the filler metal manufacturer for the specific alloy and temperature range.

How do I apply the Harris 17 Paste Brazing Flux - Eight Ounce Jar - 017FX00 correctly?

Apply flux using an appropriate method for the process: brush application for soldering and brazing fluxes (cover all joint surfaces evenly), pre-placed granular flux feeding for SAW welding. Flux quantity matters — too little flux leaves bare areas that oxidize; too much flux can be difficult to remove after welding or brazing. Apply a thin, even coat to all contact surfaces.

How do I remove flux residue after using the Harris 17 Paste Brazing Flux - Eight Ounce Jar - 017FX00?

All flux residue must be removed after completing the joint. For brazing and soldering, clean flux residue with warm water and a stiff brush immediately after the joint cools — flux becomes harder to remove as it ages. For SAW welding, remove slag and flux residue with a chipping hammer and wire brush between passes and after final welding. Confirm complete flux removal, especially in pressure vessel, pipe, and food-grade applications where residue can cause corrosion or contamination.

How should I store the Harris 17 Paste Brazing Flux - Eight Ounce Jar - 017FX00?

Store flux in a sealed container in a cool, dry location. Moisture contamination degrades paste and powder fluxes — activated flux or flux that has absorbed moisture should be discarded and not used, as it can cause porosity or incomplete flux activation during the joining operation. Keep containers sealed between uses.

Q: What is the Harris 17 Paste Brazing Flux - Eight Ounce Jar - 017FX00 used for?

The Harris 17 Paste Brazing Flux - Eight Ounce Jar - 017FX00 is a brazing flux that prevents oxidation on base metal and filler metal surfaces during torch brazing. Brazing flux is activated by heat — it liquefies at brazing temperature to coat the joint and exclude oxygen. Apply flux to all joint surfaces before heating. After brazing, remove all flux residue with warm water and a brush — brazing flux residue is corrosive and must be completely removed after the joint cools.
