Silver solder comes in 3 grades… the grades are the relative temperature flow points between one and the other. The softer the solder the less content of silver with a lower melting temperature.
Silver Solder comes in 4 different Grades of Hardness.
- Extra Soft Content of Silver 56%
- Easy Soft Content of Silver 65%
- Medium Content of Silver 70%
- Hard Content of Silver 75%
This Easy Soft Silver Solder Sheet Strip measuring 1"x 5", weight is 1/4 Toz / 5 Dwt, with a melting point of 1260o F - 682oC. with a Silver Content of 65%
Solder is Cadmium & Indium FREE
Technical Information:
Repairs: Lower temperature solder is recommended for repair work, especially on pieces that may have been reworked and a high temperature solder may cause a problem.
Assembly Work: In multiple component soldering use the Higher Temperature Solder first, then a medium grade and finally to a soft the lower melting point.
Production: High temperature solder, the Hard grade should be used, with the higher silver content, better match of color and a stronger bond. Allowing future repairs to be performed with the softer solders.
