Patent no. RO 125835 /30.07.2012<br />
BRAZING ROD made by silver alloy, with coating having<br />
deoxidation effects, deposited by extrusion. The rod alloy<br />
include Silver – C<strong>op</strong>per and Zinc, having the trade mark like<br />
BCu44ZnAg 698-810, BCu38ZnAg 650-750, BAg45CuZn<br />
660-740, and are characterised by the very high deposition<br />
coefficient, with ecological characteristics related to the<br />
covering composition, and deoxidation effects obtained by:<br />
addition of powder made by ecological metallic alloy<br />
similarly with those of metallic rod, having the grain<br />
dimension of maximum 0,1 mm, introduced in participation<br />
