The long-term service evaluation of two aluminum-brazed titanium (ABTi) honeycomb flight spoilers was concluded. The two spoilers had about years of commercial flight experience on All Nippon Airways Model aircraft. All Nippon Airways was selected because Japan has one of the most severe marine-industrial environments in the world. Service evaluation of aluminum-brazed titanium (ABTi) By S. D. Elrod. Abstract. Long term creep-rupture, flight service and jet engine exhaust tests on aluminum-brazed titanium (ABTi), originally initiated under the DOT/SST follow-on program, were completed. These tests included exposure to natural airline service environments for up to 6 : S. D. Elrod. Print View Services: Brazing service and set-up new brazing processes: Our company provides the following brazing services: (a) Vacuum brazing of metals including stainless steel, titanium, copper alloys and aluminum alloys, (b) Vacuum brazing of metals to ceramics including alumina, zirconia, silicon carbide, (c) Torch brazing of steels, copper alloys, and titanium.   Aluminum radiators as a candidate of air-cooled heat exchangers are used in automobiles due to their high thermal conductivity, lightweight, and good braze-ability. However, the corresponding brazed joint loses its strength when the service temperature goes higher than °C. Lightness, high efficiency and strength, thermal conductivity and.

aluminum has a limited zone of solid solutions with titanium that allows to count on the forma-tion of low brittle brazed joints. Another advan-tage of aluminum-base filler metals is their low liquidus—in the range of C ( F) for Al-Cu-Si brazing alloys to C . Titanium Brazing, Inc. Our company supplies Ti- or Zr-based foils or powders, Heat-resistant brazing alloys, Silver-free active powders, and Al-Mg-based foils and wires as brazing filler metals for joining titanium alloys, titanium to aluminum, copper, or steel, titanium aluminides, refractory metals, ceramics, graphite, and carbon-carbon composites in various applications such as heat. Brazed joints ot titanium were also made with the oxy-actylene torch and a commerical brazing flux. The best alloy found in torch brazing was a 45% silver, 15% copper, 16% zinc, 24% cadmium alloy, which produced shear strengths averag psi. The strengths of brazed joints in titanium . Brazing and welding are really different processes, Tigman posted about fixing his aluminum radiator useing his syncrowave, if he brought that job to my shop I would have brazed it, it's quicker, easier and very effective, I've repaired hundreds of radiators, condensors, oil coolers, you name it, useing aluminum .

Brazing-titanium is readily performed in a furnace either in vacuum or in a dry argon atmosphere with dew point lower than °C.. Titanium is one of the reactive metals, so called because they react with oxygen to form an adherent and stable oxide.. The formation of layers of titanium oxide gives to this metal and to its alloys exceptional corrosion resistance.
