Cardas Solder

George created our ultra pure, Quad Eutectic solder for the perfect joining of connector to conductor. Quad Eutectic solder contains a proprietary (i.e. we won't tell you) blend of silver, copper, tin & lead. Outside diameter: 0.032"

Counterfeit Warning:

The label on Quad solder changes with each batch. To ensure your solder is authentic, only purchase Cardas Solder through authorized dealers. If purchased through an authorized dealer, it's authentic regardless of the label.
