Low Temp Silver Solder Paste

With a melting point of 138 c and a peak reflow temperature of approximately 173 c the 670 tin bismuth paste is suitable for soldering of temperature sensitive surface mount components.

Low temp silver solder paste.

It will join 22 different combinations of metals. Low temp sn43pb43bi14 144 163 291 324 x sn42bi57ag1 138 281 x lead free. Used extensively in through hole technology assemblies in ibm mainframe computers where low soldering temperature was required. Tin bismuth and tin bismuth silver are the most common choices for low melting lead free solder pastes.

These low peak temperatures allow for soldering of thermally sensitive assemblies. Ready to use flux is blended in just add heat. This paste includes an easy to use no mess no waste syringe.

Other solder alloys are also available. The kb 430 low temperature silver paste solder has a non tarnishing white color that is ideal for repairing or creating white base metal jewelry. Use this solder on nickel nickel alloy german silver tin white bronze stainless steel brass and bronze. The 670 is a no clean solder paste.

Because of the low silver content we do not recommend using this product on silver items specifically for production as it will dilute the silver content. Low melting point flows smoothly at 430 f. Works with the heat of a torch or soldering iron. Produces small neat fillets and high strength leak free joints.

Made from premium refined powdered metals. Silver solder paste low temperature this non tarnishing product works on nickel silver tin white bronze stainless steel brass and bronze. This low temperature silver bearing solder paste will speed up soldering tasks because it works with the heat of a match or lighter. Low temperature eutectic solder with high strength.

The qualitek 670 tin bismuth solder paste has been developed for low temperature soldering. Solder it silver bearing solder paste in easy to use no mess no waste syringe. No additional flux required. Particularly strong very brittle.

Combination with lead tin solder may dramatically lower melting point and lead to joint failure.
