ABSTRACT:
A rapidly solidified brazing alloy consists essentially of about 14 to 45 weight percent magnesium and 0 to 10 weight percent of at least one element selected from the group consisting of silicon, bismuth, strontium, lithium, copper, calcium, zinc and tin, the balance being aluminum and incidental impurities. The alloy has a microcrystalline structure containing uniformly distributed intermetallic particles. It has the form of a foil (liquidus temperature <570.degree. C.) and can be used to braze non-heat-treatable rapidly solidified Al-Fe-V-Si alloy foil, sheet, plate, and tubing to produce components such as deicing duct, overduct, radiator, heat exchanger, evaporator, honeycomb panel for elevated temperature applications.
