ることを目的とする。There is also a brazing material to which Cd or Zn has been added for the purpose of lowering the melting point. Brazing is often used, and at that time, a problem arises in that Cd and Zn of high vapor pressure components contaminate the inside of the furnace. An object of the present invention is to solve these drawbacks and to provide a corrosion-resistant Au brazing alloy which is white and has a relatively low melting point.

% White brazing alloy for jewelry. In the above configuration, Au is an indispensable Au brazing alloy,
From the viewpoint of corrosion resistance, the range is from 58 to 75% by weight in order to provide an Au brazing alloy of about K14 to K18. Cu has an effect of lowering the melting point of the Au brazing alloy within a certain range, but is set to 10 to 25% by weight in view of the color tone.

めのもので、耐硫化性の面で１〜１０ｗ％とした。[0006] Ni is an element which has the greatest effect of making the Au brazing alloy white in terms of color tone, but since the melting point of the Au brazing alloy increases with an increase in the amount of Ni, 8 to 15 w%.
And Ag is used to improve the fluidity of the Au brazing alloy, and is set to 1 to 10% by weight in view of sulfur resistance.

% And Sn, if it exceeds 5% by weight, the workability for the production of the Au brazing alloy is deteriorated and the strength of the brazing using the Au brazing alloy is lowered.

%, 0.5 to 3% by weight of In, and 0.5 to 5% by weight of Sn, a white Au brazing alloy for jewelry does not contain a high vapor pressure component as compared with a conventional Au brazing alloy containing Cd or Zn. Also in brazing or brazing in a furnace in a non-oxidizing atmosphere, there is an effect that brazing can be performed without contaminating the inside of the furnace.
