Brazargent 5040

Cadmium free: 40% Ag

Description & applications

One of the most used Cd free alloy which main elements are: copper, zinc, high silver content at 40% and tin. This range has been developed to replace cadmium-bearing brazing alloys, where the use of Cd is forbidden. Tin (Sn) lowers the melting point, increases fluidity and exhibits good wetting properties. Also offer good corrosion resistance and is non-toxic enabling properties to be used in food and sanitary applications, medical fluid transport, etc.

This alloy needs a controlled quench to avoid the weakening of the brazed joint.

It is an alloy of general use, mainly used when brazing most ferrous, cuprous and nickel alloys, stainless steels and steal tools. Its excellent fluidity makes it suitable in closely fitting joints as able to penetrate tight gaps. Its fluidity together with its very close melting range makes it suited for delicate assemblies with tight clearances. Lap joints are recommended.

To be used with AG-FLUX as flux coated rods, when brazing in open atmospheric conditions.

Bare rods in Ø 1,5 - 2 - 2,5 - 3 mm, while Flux coated rods Ø1,5 and 2 mm, standard length 500 mm. Also available in wire and performs.
