BRAZING ROD made by silver alloy, with coating having
deoxidation effects, deposited by extrusion. The rod alloy
include Silver – Copper and Zinc, having the trade mark like
BCu44ZnAg 698-810, BCu38ZnAg 650-750, BAg45CuZn
660-740, and are characterised by the very high deposition
coefficient, with ecological characteristics related to the
covering composition, and deoxidation effects obtained by:
addition of powder made by ecological metallic alloy
similarly with those of metallic rod, having the grain
dimension of maximum 0,1 mm, introduced in participation
