Product Details

Choose from 4 different temperature flow points of silver wire solder.  Sold in individual coils of round wire, each coil weighing approximately 1/4 ounce (5 DWT).  The wire diameter is 0.032" (0.8mm) 20 gauge.  This silver solder is use for hard (torch) soldering (brazing) only.

Choose from:

804-400  Extra Easy (1300oF / 705oC)
804-401  Easy (1325oF / 719oC)
804-402  Medium (1390oF / 755oC)
804-403  Hard (1475oF / 802oC)

   The terms Extra Easy-Easy-Medium-Hard are used to describe the relative temperature flow points between one type or more specifically, one brand of hard solder.  Extra Easy will have a lower flow point than Easy, which will have a lower flow point than Medium, which will have a lower flow point than Hard.  This labeling system generally holds true for all brands of silver solders, but there are differences between manufactures, so you could find one makers Medium flows at the same time another makers Hard will flow.  Generally, the higher the flow point temperature, the higher the silver content of the solder.  The higher the silver content of a silver solder, the better the solder will match the color of the silver, and theoretically, the stronger the bond.

 

What temperature solder should you use?  If you are manufacturing, use the highest temperature (Hardest) solder you can so repairs may be made later with lower temperature solders.  If you are doing repairs, use the lowest temperature (Extra Easy) solder you can, since you don't know what was used before.

Here are the flow points and silver content of Otto Frei's Silver Solder:

  • 804-404 1300 F (705oC) Extra-Easy Flow
  • 804-405 1325 F (719oC) Easy Flow
  • 804-406 1390 F (755oC) Medium Flow
  • 804-407 1475 F (802oC) Hard Flow
