Silver brazing is a joining process whereby a non-ferrous filler metal, alloy is heated to melting temperature (above 800F) and distributed between two or more close-fitting parts by capillary attraction. At its liquidus temperature, the molten filler metal interacts with a thin layer of the base metal, cooling to form an exceptionally strong, sealed joint due to grain structure interaction. The silver brazed joint becomes a sandwich of different layers, each metallurgically linked to each other.
Silver brazing can employ various heat sources such as torch, flame, acetylene, gas/air, induction, resistance, infrared,oven, and furnace. Silver brazing uses filler metals and alloys such as silver, copper, zinc, cadmium, etc.
