The 555S is a universal soldering alloy for yellow gold, suitable for all karat values, designed to ensure reliability and versatility in joining processes.

It stands out for its wide range of applications, allowing use on various gauges while maintaining good fluidity and adequate chromatic integration with the base metal.

Temperature of use:
18kt: melting 760°C – flow 800°C
14kt: melting 700°C – flow 730°C
9kt: melting 675°C – flow 730°C

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

The 555S is particularly indicated for goldsmithing operations that require a versatile soldering alloy usable on multiple karat values, simplifying the management of the production process.

It therefore represents a practical and efficient solution for jewelry laboratories and productions, where flexibility, reliability, and constant quality of the result are required.
