Hard Copper Wire Solder, Hard Grade (4 ounce)

I have tested this with a butane micro-torch, but I think it doesn't get hot enough to get a good soldering. It does melt, but then it hardens too quick and it doesn't really attach to the item I am soldering (trying to solder a copper ring about 6,7 mm thick, I ma using flux too). Silver soldering works fine with this micro-torch, maybe this copper soldering needs at least a regular butane torch.

My first attempt at using a wire solder. I had no problem getting it to flow (no flux needed) and although I was very heavy handed and had to do a lot of filing (need to practice, practice, practice) it was a quick, solid solder. My only initial disappointment was that it was not copper colored. Filing made it even more gray colored. Then I read someone else's comment about reheating it to make it copper colored again. That worked!!! So if anyone reading this is having the problem of the soldered joint turning out gray (like antique silver), just reheat the joint as if you were annealing the metal, and it becomes copper colored.

I love this solder--it is the best copper solder I have found. Flows easily and (for the most part) retains the copper color so I don't have to plate my finished work. I just came back for more--I started panicking when I realized I was almost out.

This is the second time that I ordered this product and I must tell you how I am satisfied with this product and the service that I received from you. looking forward to the next order, Denis Picard

I received the order really rapidly and got exactly what I wanted. I took a chance to order from you guys since it's my first time with your company and I'm very pleased. Will order again...thank you

This was required for a copper soldering class I took.

So far I have been disappointed with this product. I have not been able to get this solder to flow. I have only been able to get it to heat into small balls that will not flow no matter how hot I get it. I did receive it in a timely manner but have not been able to use it. Very frustrating and at this point I would not recommend it. I will acknowledge that it could be a failure on my end, although I have never had a problem with other solders I have used in the past. R&T Reply: Hello Cathy, We are sorry you are experiencing frustration. Here are links to two Rings & Things' blog posts on the use of copper wire solder: http://www.rings-things.com/blog/2013/02/20/i-love-copper-solder http://www.rings-things.com/blog/2013/03/07/copper-soldering-tutorial-part-2? We have not had the problem you are experiencing, but here are a few ideas for troubleshooting: Make sure the metal you are soldering is clean. To reduce firescale forming on the surfaces you are joining, use a tripod #69-354-9. Copper wire solder does not require additional flux, but if you are having trouble with it flowing, fluxing the elements you are joining may help the solder flow. I recommend using our self-pickling flux #64-004. Make sure the metal elements you are joining have reached the solder's flow temperature of 1460?F (solder will not flow if the metal is not hot enough). I hope this helps!

It's very easy to make soldered links with this copper solder and a butane micro torch. It's nice that you don't need flux. Just heat the parts to be joined, bring the tip of your spool of solder up to the join, and fwoosh, it flows. Remember: solder is not designed to fill gaps (no matter how much I wish it worked that way), so be sure the ends to be joined have a perfect flush fit.

I am new to copper/silver smithing but I really enjoy using the wire technique to chip soldering. It looks copper after soldering but gray after filing BUT if you just heat the copper piece up again it will turn copper colored again! Most people don't realize this! It's very strong seam after soldering, I like it very much. Great price for such a large amount! ;^)
