Low Temp Silver Solder

Silver brazing produces joints that meet specifications that meet mechanical performance electrical conductivity pressure tightness corrosion resistance and service temperature.

Low temp silver solder.

Identical to the bi58sn42 solder you cite is. Solder that is composed of 56 percent silver will have a melting point of 1 145 degrees fahrenheit while solder composed of 80 percent silver melts at 1 370 degrees fahrenheit. 42 58 tin bismuth is not unknown as a low temperature solder but has issues. Produces small neat fillets and high strength leak free joints.

Excellent for use at low temperature of 430ºf 221ºc. Five times as strong as ordinary solder and will not tarnish. 4 7 out of 5 stars 119. This non tarnishing product works on nickel silver tin white bronze stainless steel brass and bronze.

Tin bismuth and tin bismuth silver are the most common choices for low melting lead free solder pastes. Cadmium free silver brazing alloys are available in paste form. It is not obvious why not given its substantial use by eg ibm. The melting point of silver solder varies depending on the chemical composition of the solder being used.

Low cost item for the model engineer who wishes to try silver brazing for the forst time or only has a very small use lowest melting point general purpose alloy a free flowing silver solder with excellent capillary properities. This group of alloys can be further broken down into the following sub groups. Contains no lead or corrosive materials. Easy to use paste dispenser contains the proper amount of solder and flux.

These alloys are similar to 63sn 37pb but use a small amount of silver to lower the melting point and to increase shear strength wetting and fatigue resistance when compared to traditional sn pb. These low peak temperatures allow for soldering of thermally sensitive assemblies. The peak reflow temperatures provided by tin bismuth alloys are low 160 170 c as compared to tin lead solders 210 220 c. Get it as soon as wed sep 30.

High production metal joining operations often employ silver brazing. More buying choices 31 89 3 new offers lucas milhaupt sil fos 15 part 95177 silver solder 7 sticks.
