A low melting (liquidus temperature <570°C.) rapidly solidified brazing alloy consists essentially of about 14 to 52 weight percent germanium, 0 to 10 weight percent of at least one element selected from the group consisting of silicon, magnesium, bismuth, strontium, lithium, copper, calcium, zinc a
A low melting (liquidus temperature <570°C.) rapidly solidified brazing alloy consists essentially of about 14 to 52 weight percent germanium, 0 to 10 weight percent of at least one element selected from the group consisting of silicon, magnesium, bismuth, strontium, lithium, copper, calcium, zinc and tin, the balance being aluminum and incidental impurities. The alloy has the form of a foil and can be used to braze non-heat-treatable rapidly solidified Al-Fe-Si-V alloy foil, sheet plate and tubing to components such as deicing duct, overduct, radiator, heat exchanger, evaporator, honeycomb panel for elevated temperature applications.
