About this product


  • A lead-free alloy solder containing a non-corrosive flux
  • Improved conductivity and flow
  • Lower melting point

Product overview

• A lead-free alloy solder containing a non-corrosive flux
• Improved conductivity and flow
• Lower melting point

This solder is 4% silver, 95.5% tin and 0.5% copper. We recommend this solder for use with the iron-clad and nickel-clad bits supplied with our soldering irons. Solder is 1mm diameter. The high silver content improves the conductivity of the solder and lowers the melting point, improving the flow.

Rated 5 out of 5 by from Been using this for at least 10 years When the world went lead free I reluctantly had to change when my old solder ran out. This product I chose as it's silver content was higher than some. Most of my work is new build or modification work and occasional repair work. At first I had to adjust to the change in use, you have to heat the soldered joint just a little longer than you would with old leaded solder to boil the flux and then it turns mirror clear. Don't forget even lead content silver solder is not a free flowing as standard non silver solder. I have never had a correctly soldered joint fail later. It's biggest downfall is it's not good if you need to resolder you have to remove all you can before you start. This is what you should do anyway . Incidentally I have 35 years experience.

Rated 5 out of 5 by from Excellent product! I had been working as a professional electronics development engineer all my career and now I am retired, electronics is my favorite hobby! When my large roll of 60/40 lead based solder ran out, I tried several lead free solders including N50aw but was always a little disappointed with the results. I bought a small amount of this solder (N51AW) and am very pleased with the results,with good flow, nicely formed shiny joints and will now use this solder with its silver content for all my future projects. I do a lot of prototyping using Veroboard and find that with a iron temperature set at 330 Deg C most components are soldered within 2-3 secs. and I have not had any problems with overheating anything including germanium diodes, Laser diodes, and many other heat sensitive components. I just wish they made it in 0.7mm gauge.

Rated 5 out of 5 by from Lead Free Solder I think you must have had a bad batch John. I too have been in the prototyping industry for 20+ years and this solder has one of the best low temp wet points and ease of flow I have used since 2006 and the discontinuation of lead solder.

Does this solder have a rosin or acid core or is it a solid core solder? Thank you

Asked by: Silver goddess
This would use a rosin based flux core.

Can you melt this onto the piece using just a soldering iron, without a torch?? I have access to an iron that goes up to 450c. I wish to solder small metal objects together. Advice much appreciated!

Asked by: Arlene
With some skill I can't see why not
