Balver Zinn i-SAC solder family

BALVER ZINN, the specialist for micro – alloyed solder presents the new tin silver based i-SAC solder family. The solidification characteristics of silver containing alloys have been upgraded by addition of Cobalt (Co). BALVER ZINN i-SAC105 (silver contents on request between 0.5 – 1.5%) combines the advantages of silver free alloys with the benefits of silver containing alloys such as, for example, SnAg3.0Cu0.5: low price, bright and shiny solder joints and fine grained microstructure. Cobalt in i-SAC-Series is responsible for a homogenous microstructure in comparison to standard SnAg alloys! In the i-SAC formulations Ge plays the role of antioxidant, preferentially reacting with oxygen to protect the solder from the oxidation that results in the formation of dross. BALVER ZINN SOLDERS i-SAC105; i-SAC205; i-SAC305; i-SAC387 are part of the new micro – alloyed lead free solder range based on SnAg.
