Brazing Various Metals

Brazing of Aluminium Pure Aluminium and certain aluminium alloys can be joined by aluminium brazing. A filler material or a brazing rod, usually, an alloy of Aluminium and Silicon of a lower melting point than that of parts to be brazed is used for aluminium brazing. One of the filler materials contains 10 to 13% silicon and melts at 5750C. This is 850C below the melting point of aluminium. It is clean and smooth flowing in action with a good penetrative and wetting power, which causes it to flow into and…
