Does anyone know if nickel plated steel tools repel molten solder any better than stainless steel?
The goal is not to reduce or prevent oxidation while soldering aluminum. The goal is to wash/float the oxides away from the surface of the aluminum. Typically, fluoride-containing salts are used.that flux has to do some serious reduction to keep ahead of the aluminum oxidizing (didn't look like they were using the reducing portion of the torch flame either)
