APPLICATIONS

Ternary silver alloy. Excellent for filling brazing. Economical. It is particularly suitable for carbon steel and cast iron. These alloys can be used as an alternative to those containing cadmium, but bearing in mind that the same silver content requires a greater heat input. With these alloys you can make all those brazing of details that will then come into contact with food or pharmaceutical products. They also ensure greater hygiene of the workplace because, being insensitive to overheating, they do not release volatile substances during brazing.
