The material is gold or gold alloy, and the brazing temperature is around 750°C. For exterior parts for watches, gold solder is used to ensure corrosion resistance; for stainless steel, a brazing material that melts at temperatures of 1000°C or higher is used, and for gold and gold alloys, it is heated at around 750°C. I'm using something that dissolves in water. To braze the main body part 22 made of stainless steel and the decorative part 21 made of gold or gold alloy, a low-temperature brazing filler metal is used and the brazing is carried out at around 750°C. As a result, the state of diffusion of the stainless steel and brazing metal is poor, resulting in a lack of long-term reliability in terms of fixing strength, and complaints are often made that the decorative parts 21 made of gold or gold alloy fall off from the main part 22 made of stainless steel and are lost. occurred. In addition, in order to improve the diffusion state, the temperature may be set high or the heating time may be lengthened.
