Difference Between Lead and Lead Free Solder

Typically, leaded solder is a mixture of tin and lead. A benefit of using this type of solder is its flowing ability as it heats up at a much lower temperature than lead-free solder, thus posing less of a thermal threat to the component.

tin to lead ratio question - Cast Boolits

Jul 19, 2011· For straight lead (IE not an alloy) with no antimony the tin limit is pretty much what you can afford. 10-1 Pb/Sn would be pricey but where such an alloy is needed would work well. When Sb is in the alloy the accepted norm in the metals industry is to use no more Sn than the percentage of Sb.

mixing in Tin with pure lead - Gunloads.com

Apr 15, 2010· Got a couple hundred lbs of pure lead ingots that I smelted back in the 60's from plumbing pipes. Back then I cast 58 cal minie balls and 44 round balls. Now I'm back to loading 38/357 SWC and WC. My Q now is how much tin would I need to add to, say 10 lb of my pure lead, to bring it up to the composition of wheel weights.? Should I spend the approx 12 bucks/lb for the pure tin in bar form, or ...

How to Buy the Right Solder for Your Electronics Projects

Soldering is used in electronics to connect metals. Solder, the soft metal that's used to create solder joints, is an alloy of tin and lead. Most solders are 60 percent tin and 40 percent lead, but that ratio may vary a bit. Although solder is wound on spools and looks like wire, it's actually a […]

Tin-lead solder alloys can be obtained with melting temperatures as low as 182 °C and as high as 315 °C. Except for the pure metals and the eutectic solder with 63% Sn and 37% Pb, all tin-lead solder alloys melt within a temperature range that varies according to the alloy composition.

Risks of Mixing Tin-lead and Lead-free

It solders perfectly well with tin-lead solders at tin-lead temperatures. The tin diffuses into the tin-lead and you get essentially a typical tin-lead joint. The Hi-Rel people have some concerns about residual pure tin exposed in the leads for whiskering, but that's only in the very exotic Hi-Rel products.
