Cardas Soldering Wire Quad Eutectic Silver Solder with rosin flux 1/4 lbs (113g) roll

As I expected. Very little silver content. This explains why the dont list it. And the rosin core stinks.

As a ten year user of this brand I am very satisfied.

Great solder for high quality audio electronics. The solder flowed very well and I didnt seem to have any cold joint issues with it. I actually preferred it to the Kester 60/40 I was using prior to it.

I use this solder exclusively on the high end studio and audiophile audio cables I assemble in the shop. While I dont know that I believe it improves audio quality, its far easier to work with than normal solder, saves me time in production (especially when its high volume), and creates very strong joints that resist corrosion. My understanding is it will improve corrosion resistance long term, and it seems to. Ive also never had a failed joint with this solder, on any of the thousands of cables I made (and some musicians are very abusive to cables). So while Ill use Multicore solder for my electronics prototyping and Kester for regular jobs, anything really important strength- and signal- wise usually gets Cardas. And its made here in Oregon, which I love.

Excellent for Hifi cables

This is top notch. You may find better and I would ask that you post your response if you do.

I really wanted to like this solder since most of what I do is geared towards audio. I design and build class-D amplifiers and speaker systems and like the idea of using silver solder. I have used Radio Shack silver bearing solder for years and it has been my go-to silver solder for audio and surface mount work. This solder behaves very much like lead-free solder even though it is labeled as having lead content. It really doesnt want to stick to anything, even the soldering iron tip, and just beads up into a ball and falls off the solder wire. It even has trouble soaking into fluxed de-soldering braid. I cant really recommend this solder but for best results use higher heat and a LOT of flux.

Just did an Elekit single ended tube amp kit. Used Kester for the structural solder. But I sprung for the best for any joints in the signal path. This stuff is great to work with. Do you really want to wonder What if?, Nah, just use the good stuff for your music, you deserve it.

*** Not cheap...but excellent Silver Solder ****

I needed something that sounded better than regular solder. This is the best sounding solder Ive found. If you care about audio buy this solder. It is a littler harder to use, however it will be worth the price and effects. Once you hear the fine details in your music you will not go back to regular solder.
