Abstract
The invention proposes a brazing alloy, which can be produced in particular as a homogenous, ductile, amorphous brazing foil and consists of 2 to 20 atom % of nickel, 2 to 12 atom % of tin, 0.5 to 5.0 atom % of zinc, 6 to 16 atom % of phosphorus, remainder copper and incidental impurities. The total amount of copper, nickel, tin and zinc is between 80 and 95 atom %. The addition of more than 0.5 atom % of zinc produces excellent resistance to surface oxidation in air and/or atmospheric humidity. These brazing alloys can be used to produce excellent brazed joints.
