Low Temperature Silver Solder

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.

Silver brazing produces joints that meet specifications that meet mechanical performance electrical conductivity pressure tightness corrosion resistance and service temperature. Silver brazing frequently called hard soldering or silver soldering is a low temperature brazing process with rods having melting points ranging from 1145 to 1650ºf 618 to 899ºc. Easy to use paste dispenser contains the proper amount of solder and flux.

In specific proportions some alloys are eutectic that is the alloy s melting point is the lowest possible for a mixture of those components and coincides with the freezing point. This is considerably lower than that of the copper alloy brazing filler metals. More buying choices 31 89 3 new offers lucas milhaupt sil fos 15 part 95177 silver solder 7 sticks. Soldering performed using alloys with a melting point above 450 c 840 f.

Tin bismuth and tin bismuth silver are the most common choices for low melting lead free solder pastes. Cardas soldering wire quad eutectic silver solder with rosin flux 1 4 lbs 113g roll. Five times as strong as ordinary solder and will not tarnish. High production metal joining operations often employ silver brazing.

The peak reflow temperatures provided by tin bismuth alloys are low 160 170 c as compared to tin lead solders 210 220 c. These low peak temperatures allow for soldering of thermally sensitive assemblies. 720 k is called hard soldering silver soldering or brazing. This group of alloys can be further broken down into the following sub groups.

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. Free shipping by amazon. Contains no lead or corrosive materials. Cadmium free silver brazing alloys are available in paste form.
