K-T Industries rosin-core solder wire, 40/60 tin-lead alloy, supplied as a 1/2 lb spool. The 3/32" diameter is the most versatile size in the K-T lineup - heavy enough for chassis wiring and terminal work, fine enough for general electronics.

• Alloy: 40/60 tin-lead with rosin flux core
• Wire diameter: 3/32"
• Spool weight: 1/2 lb
• Pre-fluxed - no separate flux required for clean copper
• Suitable for electrical splices, terminal lugs, switches, and general electronic projects

Tip: Lead-bearing solder. Work in a ventilated area, do not eat or drink at the bench, and wash hands after handling. Step up to the 1/8" (1 lb) spool for larger gauge work, or down to 1/16" for fine PCB and component leads.
