Review on 💎 Stay-Brite STAR2000 SBSK Silver Solder 3/64, 1/2 oz"+ by Virgilio Feliciano

UPDATE OCTOBER 25, 2017: Although acid flux on the bottle says it's not recommended for aluminum (don't know why), it *works* on aluminum! I just soldered some aluminum grommets to the body of the cordless drill and it worked great! Without acidic flux, heat or good resin core solder it will work. However, once I applied a little acidic flux to a clean surface, it stuck instantly! Surface to be joined *first*, apply solder to the iron (regular resin core electronics solder will work, or acid core solder will also work) and place the hot iron on the aluminum surface. Boom! The heat from the acidic flux will corrode the surface a little and the solder on the iron will immediately bond to the aluminum surface! Rinse the parts thoroughly when you're done to wash away as much of any remaining acidic flux as possible so it doesn't further eat away at your joints. saved my day! ORIGINAL REVIEW OCTOBER 1, 2016: Works on broken/worn stainless steel bike cables (for brakes, derailleurs, etc.). My old car has cruise control after sale as it didn't have cruise control. The cruise control has a small coiled stainless steel bike cable that attaches to my car's throttle to control the gas pedal. However, this cable broke about 1.5 years ago. I had no idea how to fix it and numerous car services said there was nothing they could do. I finally came across this flux and solder kit. Previous attempts to solder any type of steel like this wire have been futile as oxidation (I think that was the problem) prevents bonding and the rosin fluxes I had didn't work. A drop of this flux on the end of the cable plus my handy 60w soldering iron did the trick. Excellent flux. The container is supplied with a folded sheet of paper containing the Safety Data Sheet. It says: Stay Brite Solder Wire Composition: Ag: 3.4-3.8%, Sn: balance. This means that this solder is a Sn/Ag mixture of about 96.4/3.6. In other words, it is 96.4% tin and 3.6% silver. This is a high quality lead free solder, although I'm sure any standard solder will also work well with the flux included in this kit such as: B. 60/40 60% Sn (tin) / 40% Pb (lead) with lead. Solder or 99.3% Sn (tin) / 0.7% Cu (copper), lead-free solder. % Ammonium Chloride: 5-25% Hydrochloric Acid: <5% Methanol: <5% Water: Residue Taking a few guesses from the information above means this acid-based flux could look something like this: 30% zinc chloride, 15% ammonium. chloride, 5% hydrochloric acid, 5% methanol, 45% water. METALS SUITABLE FOR THE FLUX: The flux bottle states that this stay-clean flux is suitable for "all soldering purposes", specifically that it is excellent for working with copper. Tubing, brass, bronze, stainless steel, nickel [nickel plated steel] and zinc plated [ie cink steel]. Not recommended for aluminum or electrical/electronic applications. I don't know why it's not recommended for aluminum, but I think it probably isn't recommended for electrical/electronic applications simply because it's a corrosive acid-based flux and may not allow the circuit to last as long as desired . otherwise if the acid stays on the board. However, if you wash off the excess flux afterwards I'm sure it's fine and if I ever need to re-solder a spring steel battery adapter or battery holder spring or similar corrugated steel connection I will definitely be using this 1st flux on those electrical application as I don't know of any other way to connect the solder to such materials. In such cases, an acidic flux is required. Have fun soldering! Gabriel Staples ElectricRCArcraftGuy
