Cardas Quad Eutectic Solder
- 1 x 1/4 pound roll of 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).

Very easy to use, flows nicely with my Antex iron. One reel goes a long way, so far soldering three Biamp 6-24 crossovers, four ACA minis, three soft start boards and several field coil power supplies and there’s still more on the reel.
Not really a review but an endorsement. I've use about ten different solders, most with a high silver content and no lead. Cardas Quad is by far the easiest to use and the results are consistently good conductivity and appearance. No faults that I can point to.
I replaced my old 60/40 solder with this Eutectic solder from Cardas and what a difference to work with.
Just tried it on some boards and will not go back to my old solder even though still some are left of that.
And the silver portion also gives a great shining on each solderpoint on the boards.
I purchased the quad eutectic Cardas solder after being given a sample from a friend. I did some measurements and it does make lower resistance connections than conventional 63/37 solder and is slightly better than the alloy that has 2% silver. That said, it has just the right amount of rosin and flows nicely. I'd even use it on high current connections that are not audio related.
everyone knows this is the standard when working with fine soldering jobs for their turntables.
