The 339S is a specific soldering alloy for 18 kt yellow gold, designed to ensure high precision and control in joining processes.

It stands out for its very narrow temperature range, allowing for accurate soldering management, reducing the risk of deformation or overheating of the piece.

Temperature range for use:
18 kt: melting point 784°C – flow point 790°C

From an operational point of view, the alloy offers good wettability and uniform distribution, allowing for clean, resistant, and perfectly integrated joints from an aesthetic point of view.

The 339S is particularly indicated for precision work on 18 kt yellow gold, where a very fine thermal control and a high-quality result are required.

It therefore represents an ideal solution for high-level goldsmithing applications, where precision, reliability, and impeccable finish are required.
