SILVER BRAZING ALLOYS CADMIUM BEARING

The brazing alloys presented in this page are very versatile, high-strength, free-flowing and exhibit the lowest melting points of all silver based alloys.
They can be used to join a wide range of base materials.
Continuous service operating temperatures of jointas brazed with these lloys range up to approx 200°C.
Because of the presence of Zinc and Cadmium, and the possible failure of the joint due to the mechanism of interfacial corrosion, these alloys are not recommended for the joining of steinless steels in wet conditions; in these conditions, Zinc free and Cadmium free alloys, or alloys with Nickel additions are preferred: see Silver Brazing Alloys – Special Applications.
Since Cadmium and its oxides are toxic, special safety precautions must be followed during brazing operations (e.g. mechanical ventilation and/or respiratory mask).
The use of these alloys in applications where food, beverages and/or human health in general is involved, is forbidden.

CADMIUM BEARING BRAZING ALLOYS HAVE BEEN BANNED IN THE EUROPEAN UNION SINCE DECEMBER 2011 (EU COMMISSION REGULATION NO. 494/2011) AND THEIR USAGE IS NO MORE ALLOWED: PLEASE CONTACT OUR TECHNICAL AND COMMERCIAL STAFF TO GET AN ADVICE ON SELECTING THE MOST APPROPRIATE CADMIUM-FREE SUBSTITUTES.
