SILVER BRAZING ALLOYS

This group of alloys is in accordance with the new environmental rules and replaces the old group of silver alloys with cadmium.
The use of these alloys guarantees compliance with the Community rules regarding the "Reach" regulation and with more ecological guarantees, both in terms of the operator and in its structural application, not affecting in any way any environmental contamination.
Low temperature alloys are particularly suitable for brazing all types of materials such as: copper / steel, steel / steel, steel / nickels, and other materials between them.
This type of brazing addition material makes it possible to obtain joints with high mechanical resistance, ductile and without toxicity to humans.
