Description of the Related Art Conventional Ag-Cu-Ti based active metal brazing alloys are used for long-term exposure in the air or oxygen atmosphere after brazing, and also in high temperature or high temperature conditions. Parts that are subjected to frictional heat and parts for electric furnaces have poor oxidation resistance, so that they are oxidized by oxygen and the strength of the brazed portion becomes weak. This is because Ag passes oxygen and Cu
Is oxidized.

The present invention aims to provide an active metal brazing material having improved oxidation resistance (corrosion resistance).

性が悪くなるからである。The oxidation-resistant active metal braze of the present invention for solving the above-mentioned problems is formed of Ag-Cu-Ti.
At least one of Sn or Al is added to the active metal brazing material.
It is formed by adding 0.5 to 20%. The reason why 0.5 to 20% of at least one of Sn and Al is added is that if it is less than 0.5%, there is no effect of improving the oxidation resistance, and if it exceeds 20%, the workability deteriorates.

による強度劣化が生じない。When ceramics, inorganic materials, ceramics or an inorganic material and metal are brazed using the oxidation-resistant active metal brazing material of the present invention having the above-mentioned structure, the brazing part partially oxidizes the surface in the initial stage. Immediately, Sn and Al prevent oxygen permeation, and oxygen does not further penetrate into the interior, so that strength deterioration due to oxidation does not occur.
