Product Details

4% Silver Solder 1/2 lb. Spool

Why bother spending more on high-end speakers and boutique crossover components to only have their sound dulled by standard lead/tin solder. Silver solder consists of 4% silver and 96% tin to provide greater electrical conductivity than standard solder and allows miniscule microphonic signals to make their way through the crossover and to your speakers. Signal distortion is also said to be reduced when using silver soldered joints, and performance is optimized at all frequencies for consistent, exact sound reproduction. Halogen-free flux allows for working with precious metal surfaces with little to no degradation. Lead-free.

Specifications: • Melting temperature: 422.6°F/217°C • Solder diameter: 1.0 mm Spool weight: 1/2 lb.

4% Silver Solder 1/2 lb. Spool
4% Silver Solder 1/2 lb. Spool is rated 4.0588 out of 5 by 17.
Rated 5 out of 5 by from Lead free silver solderThis solder works great. I was unsure when I received the package with it stating that this solder was lead free but the quality and thickness of the solder is very good.

Rated 5 out of 5 by from Excellent product.I purchased this product for use in repair of RF producing products; primarily for the higher melting temp and silver is great for conducting.

Rated 5 out of 5 by from Used 40w ironUsed a cheap 40w radioshack iron to solder balanced XLR cables with great success. Cables sound great. Coated wire and contacts with extra flux and had zero flow problems. 40w may be a bit too high for electronics, but obtained great flow and great looking joints with this wattage. My 25w iron was not melting the solder.

Rated 1 out of 5 by from DissapointedFirst let me state that I am a long time PE customer and have been very pleased with the products and support. This solder has a high temp melting point whichin my opinion is not good for any kind of electronic/cable making work. It alsocools to a dirty gray color which does not instill much confidence. I have gone back to Cardas Quad Eutetic which I like better than WBT. I'll relegate the PE solder to sweating pipe joints.

Rated 5 out of 5 by from Great Price for Silver / Lead Free SolderI have used a lot of these reels (15+) and they are great value for money and give a good solder joint.It would be even better if a smaller gauge solder reel was offered as I find that some jobs require a thinner solder wire.Will continue to purchase these...Thanks!

Rated 4 out of 5 by from Excellent Price for a 4% Silver SolderHalf the price of equivalent silver solders, but performs almost as well as higher-priced versions, which is VERY GOOD.For those that aren't aware, the higher the silver content, the higher the melting point. I use a soldering station specifically designed for unleaded solders so it's not an issue. If you're iron is on the edge of having enough oomph, you might want to use a standard solder with a lower melting point.
