Cardas Quad Eutectic Solder

We are pleased to offer Cardas Quad Eutectic solder.   A number of DIYers name it as their favorite solder.  Some information from Cardas is below. Description: A proprietary blend of copper, silver, tin, and lead. Proprietary as in "please don't ask for the recipe because we're not telling, and we don't want it to get weird." No other solder flows as well, solidifies as uniformly, sounds as good or provides as durable and long lasting solder joints. There's a reason Quad Eutectic is considered the best in audio, and is widely used outside of our industry as well. Quad Eutectic Solder was developed in the early days of Cardas Audio when George Cardas realized that the available solders on the market - from hardware store grade to expensive silver-heavy solders - all had shortcomings that lead to degradation in sound quality & long-term reliability. He worked with an English metallurgist to arrive at the perfect blend of elements.  The four elements in Quad Eutectic Solder are in specific proportion to melt and solidify at a temperature lower than that of any of the component metals! Thus the resultant joint is contiguous from wire to connector rather than slurry - this provides a perfect and permanent connection that will never breakdown over time. Quad Eutectic Solder has a rosin core, and has a melting point of 350ºF (177ºC).
