SRA No-Clean Flux Core Solder – 63/37 .031" Diameter, 2 Oz Spool, Melts At 361°F

About This Product

This SRA solder is a solid all-purpose choice for electronics work.

It's a 63/37 tin-lead blend with a no-clean flux core, so you get great wetting and flow without having to scrub off residue afterward—the flux is non-corrosive and non-conductive, so it's safe to leave on most circuit boards.

The diameter is .

031 inches, which is a sweet spot for through-hole work, component leads, and general soldering on PCBs.

It melts at 361°F (183°C), which is standard for 63/37 eutectic solder, giving you a nice sharp melting point for clean joints.
The 2-ounce spool is a good size for hobbyists or bench techs—not too huge, not too small.

Whether you're repairing a vintage radio, building a kit, or fixing a keyboard, this solder flows smooth and holds up.

Reliable, consistent, and does exactly what it's supposed to.
