Lead Free Solder Wire
Lead-Free Solder Wire
A complete lead-free solder wire series covering SAC, tin-copper, tin-antimony, high-purity tin and low-temperature tin-bismuth alloy systems for electronics and industrial soldering.

Lead-free solder wire for electronics and industrial joining
Jufeng supplies lead-free solder wire in multiple alloy systems and wire configurations. Options include widely used SAC305, low-silver SAC, eutectic tin-silver, multiple tin-copper grades, higher-temperature tin-antimony, high-purity tin and 138–139°C low-temperature solder wire.
Multiple Alloy Families
Select SAC, Sn-Cu, Sn-Sb, high-purity Sn, Sn-Bi or Sn-Bi-Ag wire according to the process.
Fine Diameter Capability
Selected SAC305 solder wire can be supplied from 0.1 mm for precision soldering and repair.
Flux-Cored & Solid Options
Choose built-in flux convenience or solid wire for separate flux control, subject to alloy and diameter.
Low-Temperature Series
Sn42Bi58 and Sn-Bi-Ag options support joining around 138–139°C.
Packaging Flexibility
Tube, multiple spool weights, cartons and private-label options can be discussed.
Technical Selection Support
Alloy, diameter, flux and packaging are confirmed against the customer process before production.
