Review on 🔩 Blue Demon BDTP-125-01T Triple Play Low Temperature Aluminum-Zinc Brazing Rod 1/8 Inch x 18 Inch 1 Pound Tube by Scott Ward

I used these Zinc Aluminum Solder Rods when I needed to make my own fascia around a skylight. I electroplated regularly and these soldering sticks worked. They braze both aluminum and zinc. But the aluminum pad is too thin and melts too easily. Galvanized content works well. Here are some tips: Flux is not needed, but if the surface is dull or dirty, clean it with a STAINLESS STEEL wire brush. Ordinary wire brushes will not work. Prepare each surface by "tinning" which means melting a thin layer of solder on the surfaces before actual soldering. This is very important for a good strong connection. A regular propane lamp is quite hot, but a wider flame works better than a pencil-tipped flame. Always heat the metal and allow the metal to melt the solder. Don't melt the soldering iron with the flame itself. The trick is to keep the temperature around 750F. Too hot and the metal can burn and warp. Too cold and the solder will not melt or stick together. Use clamps to hold the surfaces together. This alloy fills small gaps but works best when the gaps are narrow. Do not hurry. Practice on scraps first.
