Abstract: A powder admixture of 97.75% minus 325 mesh atomized alloy powder, which has a composition (by weight) of 94.12% copper, 2.81% silicon, 3.07% aluminum, and 2.25% minus 325 mesh titanium hydride powder is disclosed. The powder is used to form a brazing alloy for brazing ceramics.
Abstract: A brazing alloy system having a brazing temperature of 1025.degree. to 1080.degree. C., a solidus temperature above 1000.degree. C., a liquidus temperature above 1018.degree. C., consisting of, in weight percent, 5-30 Au, 15-35 Pd, 10-30 Ni, 20-48 Cu, and 15-25 Mn. Preferred brazing alloys are (1) 25 Au, 15 Pd, 18 Ni, 31 Cu, and 11 Mn, (2) 5 Au, 30 Pd, 10 Ni, 40 Cu, and 15 Mn, and (3) 15 Au, 20 Pd, 13 Ni, 41 Cu, and 11 Mn.A method of joining superalloy parts using these alloys as a braze is disclosed, as well as a panel made of a honeycomb structure of thin superalloy metal sandwiched between two sheets of superalloy and brazed with these alloys.
