The 778S is a solder alloy for red gold, suitable for 18kt and 14kt titles, designed to offer precision and control in joining processes.

It stands out for relatively low working temperatures, which reduce the risk of overheating the piece while maintaining good solder quality and adequate chromatic integration with red gold.

Usage temperatures:
18kt: melting 730°C – flowing 750°C
14kt: melting 700°C – flowing 740°C

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

The 778S is particularly indicated for goldsmithing operations where good thermal control and reliable soldering on red gold at various titles are required.

It therefore represents a practical and efficient solution for jewelry laboratories and productions, where precision, quality, and continuity in results are required.
