Joining of Alumina/Alumina Using Al-Cu Filler Metal and Its Application to Joining of Alumina/Aluminum(Materials, Metallurgy & Weldability)
The wettability of aluminum-copper alloys on alumina was investigated by a sessile drop technique in a vacuum, and the joining strength of alumina/alumina joint brazed with the aluminum-copper fillers was related to the wettability of the alloys. Further, alumina was metallized with aluminum or aluminum-4mass% copper alloy filler, and brazed to A1050 aluminum in a vacuum. The aluminum-4mass% copper filler provides the superior joining strength of 157MPa for alumina/alumina joint, and 80MPa for alumina/A1050 joint.
