K813S is a soldering alloy for white gold, suitable for 18 kt and 14 kt fineness, designed to ensure reliability and good joint quality in jewelry manufacturing.

It is characterized by relatively high working temperatures, making it suitable for operations where good mechanical strength and joint stability are required during subsequent processing stages.

Working temperatures:
18 kt: melting 870°C – flow 830°C
14 kt: melting 850°C – flow 850°C

From an operational standpoint, the alloy provides good wettability and uniform material distribution, allowing for clean, strong, and aesthetically well-integrated joints.

K813S is particularly recommended for white gold applications where reliable soldering across multiple fineness levels is required, maintaining consistent performance and quality.

It therefore represents a versatile solution for jewelry workshops and production environments where strength, precision, and consistency are essential.
