Tin-copper lead-free low temperature solder has a faster melting range allowing for rapidly filling small, tight-fitting pipe connections with free flowing properties used to join copper pipe in potable water systems.


97/3 (Speedy) tin-copper solder has a faster melting range allowing operators to rapidly fill small, tight-fitting, pipe connections. Its low temperature and free-flowing properties reduce cycle time and required heat input. 97/3 is available in acid core, rosin core and solid wire versions.


  • 97/3 tin-copper solder is environmentally safe with no lead or antimony
  • Melting temperature of 445°F (229°C)
  • 5800 psi tensile strength
  • Melts, flows and performs better than 95/5 solder
  • Made in the USA with global components

Typical Applications

  • Plumbing
  • Copper pipe joining and repairs
