    Good clean solder. Very pleased with how it worked.

  2. Doug (verified owner)

    Good product , outstanding service

  3. Chris Hanson

    Best prices out there in quality solder. This solder flows so well I recommend you buy the thinnest bars. The big bars will flood a 20oz copper joint quickly if you don’t watch out.

  5. David Ciriaco (verified owner)

    Quality solder. Different selection of sizes is great for different applications. Also, no minimum helps out smaller operations from having to buy $500 worth when they rarely solder.

    Quality and shipping time are on the mark!

  22. Richard Brandolini (verified owner)

    Great clean solder. I like the heavier bars, they go further when soldering. They were shipped in 3 days making them readily available on the job I needed them for. The price was very good, I will definitely order more products from this company.

  23. Gene Drake (verified owner)

    I am not a roofer, I cast bullets for reloading. As the wheel weights are melting a bar of 50/50 solder is added to the mix. This makes the mix a correct hardness. When looking for source of 50/50, I came across this company. I found the price was very good and delivery was great. I will recommend the company to other reloading people. Thank You!
