The 773S is a universal solder alloy for yellow gold, suitable for all karat weights, designed to offer versatility and reliability in various joining processes.

It stands out for its ability to adapt to different karat weights, maintaining good performance in terms of fluidity and chromatic integration with the base metal.

Usage temperatures:

18kt: melting 750°C – flowing 800°C
14kt: melting 710°C – flowing 780°C
9kt: melting 710°C – flowing 770°C

From an operational standpoint, the alloy ensures good wetting and uniform distribution during soldering, allowing for clean, resistant, and aesthetically pleasing joints.

The 773S is particularly indicated for jewelry manufacturing that requires flexibility in use on various gold alloys, reducing the need to use specific solders for each karat weight.

It therefore represents a practical and versatile solution for workshops and goldsmithing productions, where simplicity of use, reliability, and consistent quality of the result are required.
