The 22ST is a solder alloy designed for 22 kt yellow gold, intended to ensure precision and reliability in joining processes.

It features a melting point of approximately 740°C and a flow point of approximately 720°C, allowing for good control during the soldering phase, promoting a correct material distribution and good wetting.

From an operational standpoint, the alloy offers good fluidity, enabling the achievement of clean, resistant, and aesthetically well-integrated joints with 22 kt gold.

The 22ST is particularly suitable for jewelry manufacturing where precision, soldering quality, and uniform chromatic yield are required.

It therefore represents an effective solution for high-karat gold applications, ensuring process reliability and high-quality results.
