The K413S is a solder alloy for white gold, suitable for 8kt and 14kt titles, designed to provide versatility and reliability in joining processes.

It stands out for a good balance between melting and flowing temperatures, allowing for effective control of the soldering process and good integration with various carat weights.

Usage temperatures:
14kt: melting 800°C – flowing 820°C
8kt: melting 830°C – flowing 830°C

From an operational point of view, the alloy offers good wettability and uniform material distribution, allowing for obtaining clean, resistant, and aesthetically well-integrated joints.

The K413S is particularly indicated for working on low to medium gold white, where a versatile and reliable soldering is required, usable on multiple carat weights.

It therefore represents a practical solution for goldsmithing laboratories and productions, where flexibility, constant quality, and ease of use are required.
