   [citation needed] The metal ions, more noble than aluminium, then undergo a redox reaction, dissolve the surface layer of aluminium and form a deposit there. This intermediate layer of another metal then can be wetted with a solder. One example of such flux is a composition of triethanolamine, fluoroboric acid, and cadmium fluoroborate. More ...
