Abstract

PURPOSE: To obtain brazed joint and brazed alloy having high creep strength, by constituting te brazing part of which one side at least is copper substrate with an alloy having liquid phase temperature of less than softening temperature of the copper substrate and having an inermetallic compound formed therein.
CONSTITUTION: The liquid line of an alloy of brazing of metals of which one at least is copper or copper alloy and other metal should be less than 350°C, not causing the copper to soften. As the brazing alloy to form intermetallic compound, Au-Sn, Au-In, etc. are considered. When brazing with such brazing alloys, eutectic structure crystallizes, and intermetallic compound may be formed around the eutectic crystal. Therefore, the tensile strength and creep rupture strength of the joint part may be improved.
