MG Chemicals Lead Free Solder 96 Sn

Greater Strength For Component Joining

Low Price Guarantee


What's special about this solder?

  • Silver solder has a greater strength in joining components than lead solder, making it ideal for use in applications where vibration is a factor
  • Meets the impurity requirement for J-Std-006 and RoHS which means free of lead and other potentially hazardous substances such as mercury
  • No clean solder residue means when you are finished soldering you have a hard, non-conductive residue left behind which does not require any cleaning
