The 777S is a universal soldering alloy for yellow gold, suitable for various karat weights, designed to ensure versatility and reliability in joining processes.

It stands out for its good adaptability to different thicknesses, offering correct fluidity and good chromatic integration with the base metal.

Temperature of use:
18kt: melting 740°C – flow 775°C
14kt: melting 650°C – flow 730°C

From an operational point of view, the alloy ensures good wetting and uniform distribution during soldering, allowing for clean, resistant, and aesthetically well-integrated joints.

The 777S is particularly indicated for goldsmithing operations where a versatile soldering is required, capable of adapting to multiple karat weights while maintaining quality and reliability.

It therefore represents a practical solution for laboratories and jewelry production, where ease of use, process control, and constant quality of the result are required.
