metals that can be soldered
Posted. Basically all metals can be soldered, but we are talking about a low melting point soft solder and a flux common to stained glass. With the soft solders and a zinc chloride flux (most common), these metals will bond very easily: copper, tin, and brass. These metals will NOT bond: Iron, stainless steel, steel, and aluminum.. Boris: I agree with most of your list (add some bronzes to the yes list), but steel CAN be soldered with soft solder.
