Title:
METHOD FOR BRAZING ALUMINA DISPERSION STRENGTHENED COPPER
Document Type and Number:
WIPO Patent Application WO/2020/022046
Kind Code:
A1
Abstract:
[Problem] To realize brazing of alumina dispersion strengthened copper. [Solution] GlidCop (registered trademark), which is alumina dispersion strengthened copper, and another metal are prepared, and surfaces thereof to be joined are finished to a fine mirror finish, after which a BNi-6 brazing material, which is a nickel alloy containing 11% phosphorous, is sandwiched between the surfaces, and pressure is applied. In this state, heat treatment is performed for 10 minutes at a heat treatment temperature of 960°C. After adequate natural cooling, quenching is performed using nitrogen gas. In this way, brazing of the alumina dispersion strengthened copper and the other metal can be realized.
