Silver Solder Sheet Kit

This kit contains one small sheet each of three different flowing Cadmium Free silver solders: 804-405 Soft (1260oF) Flow Point 804-406 Medium (1295oF) Flow Point 804-407 Medium-Hard (1375oF) Flow Point   .  The total weight will be approximately 15 pennyweights.   The terms Extra Soft, Soft, Medium, Medium-Hard, and Hard are used to describe the relative temperature flow points between one type or more specifically, one brand of hard solder.  Extra Soft (also called Extra-Easy) will have a lower flow point than Soft (also called 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.
