How do I remove stay Silv flux?
Stay Silv white or black brazing flux residue can usually be removed by washing or immersing the part in water immediately after brazing. Brushing or swabbing the brazed area in conjunction with the water quench may help remove stubborn residue. Care should be taken in cleaning joints involving dissimilar metals.
What is stay Silv?
It contains both borax and flourides for excellent cleaning while molten. I’ve used this product for decades. 1.0 out of 5 stars Not a choice for real silver. So if you are working with solid silver stay silv can be tricky and the fumes from it are overpowering even with proper ventilation.
What is white flux used for?
White flux is useful for brazing copper, brass, steel, stainless steel and nickel alloys. It has an active temperature range of 1050° -1600°F (565° – 870°C).
What is white brazing flux made of?
White Brazing Flux- Standard high temperature brazing flux White Brazing Flux is a combination of Potassium salts of Boron and Fluorine.
Why must you clean off the excess flux after brazing?
11 Flux Residue Removal in Brazing and Soldering In general, it is necessary to remove flux residues remaining after brazing and soldering applications because they may be corrosive and prevent finishing operations such as painting or chromium plating from being successfully completed.
How do you remove flux after welding?
The most common methods for post-braze flux removal are: Soaking/wetting – Use hot water with agitation in a soak tank to remove excess flux immediately following the braze operation, and then dry the assembly. When soaking is not possible, use a wire brush along with a spray bottle or wet towel.
How do you use stay Silv flux?
STAY-SILV® POWDER BRAZING FLUX The flux can be used in its powder form by heating the end of the brazing rod or wire and dipping it in the flux. The flux will adhere to the heated rod. The flux can also be mixed as needed with water or alcohol to form a paste. The paste can be applied to the part prior to brazing.
Do you use flux with Stay Silv 15?
When heated above its liquidus temperature, however, it will flow into tight connections. Stay Silv 15 can be used to braze brass with the use of appropriate brazing flux.
What is white flux?
White Flux or Alcoholic flux, is a stress-related disease that affects sweet gum, oak, elm and willow trees. The disease is caused by a microorganism that ferments the sap that seeps or bleeds from cracks and wounds in the bark. The result is a white, frothy ooze that has a fermenting odor similar to beer.
Can you use borax for brazing flux?
Borax-based fluxes: In addition to being a common ingredient in detergents and many other products, borax has long been used as a flux in welding processes, including brazing. Borax improves the flow of filler metals and reacts with certain oxides to lower their melting points.
What is the most commonly used form of brazing flux?
These fluxes are manufactured in a variety of forms – powder, paste or liquid (for spraying). The most convenient form of flux to use when brazing with a torch or by induction is paste. Paste fluxes should have a creamy consistency with a viscosity like that of house paint.
