The K81S is a specific soldering alloy for white gold 8-12 kt, designed to ensure high joint strength and stability during jewelry manufacturing.

It stands out for its high usage temperature and coinciding melting and flowing points, allowing for precise control of the soldering phase and rapid material solidification.

Usage temperatures:
8 kt: melting point 940°C – flowing point 940°C

From an operational standpoint, the alloy offers good wetting properties and enables the formation of compact, strong, and well-integrated joints, particularly suitable for applications requiring robustness.

The K81S is particularly indicated for applications on white gold 8 kt where high-temperature soldering is required, such as in initial assembly phases or on components subject to subsequent thermal processing.

It therefore represents an ideal solution for technical jewelry applications, where joint strength, precision, and reliability are required.
