RUKO LOS-HM-16.5mm Solder Wire Sn60Pb40 1mm 250g

Soldering electronics can be frustrating when the solder doesn't flow smoothly or leaves messy residues. The RUKO GMBH LOS-HM-16.5mm solder wire solves this with a reliable tin-lead alloy and a no-clean rosin flux that ensures strong, clean joints for general electronics work, repairs, and hobby projects.

Who is it for

This solder wire is ideal for electronics technicians, repair professionals, and hobbyists who need a dependable solder for through-hole and general wiring tasks. It is especially suited for applications where lead-based solder is still permitted.

Main features

• Alloy composition: Sn60Pb40 (60% tin, 40% lead) provides a good balance of melting point and joint strength.
• Wire diameter: 1.0 mm, suitable for standard soldering tasks.
• Flux type: Rosin-based, no-clean flux with 2.5% content, leaving transparent, non-corrosive residues.
• Halogen-free flux for safer soldering.
• Spool weight: 250 g, convenient for regular use.
• Melting point: 183–190 °C, compatible with common soldering irons.
