Three small spools of silver-grey solder wire on a light surface

3Pcs Solder Wire 63/37 0.8mm 36g

SKU CH-5XKZ-4BY90

Three spools of 63/37 tin-lead rosin-core solder wire, 0.8 mm diameter and 36 g each, melting at 361 °F for low-residue electronics work

  • 63/37 alloy melts at 361°F for fast, even flow on circuit boards
  • 8 mm diameter wire feeds precisely through fine-pitch components
  • 8 % flux core leaves low residue after soldering
  • 36 g net weight per spool supports multiple repair jobs
  • Three spools included for bench stock or shared projects

63/37 tin-lead solder wire

This pack contains three spools of 63/37 tin-lead alloy solder wire with a rosin flux core. Each spool weighs 36 grams and the wire diameter is 0.8 mm. The alloy melts at 361 °F for quick, even flow during hand soldering tasks.

Check flux compatibility and lead handling

Verify that rosin flux residue is acceptable for your assemblies and that you can follow lead-safety procedures. The flux content is 1.8 % by weight and the product contains lead, which requires ventilation, hand washing and proper disposal in line with local regulations.

Low-residue core and practical diameter

The rosin core leaves minimal residue, reducing cleaning time on boards and component leads. At 0.8 mm the wire suits through-hole joints and larger surface-mount pads, while the 36 g spools are easy to handle during extended repair sessions.

Questions about this item

What comes in the pack and is there anything else I need to start soldering?

You get three spools of 0.8 mm 63/37 rosin-core solder wire, each 36 g net. The flux is inside the wire at 1.8 %, so no separate flux is required; you only need a soldering iron.

Why would I pick the 0.8 mm 36 g spools instead of a thicker or heavier option?

The 0.8 mm diameter suits fine-pitch work on circuit boards, phone boards and small components, while the 36 g spools keep the bench tidy and avoid waste on occasional jobs.

What does the 361 °F melting point mean when I am actually at the bench?

The 63/37 alloy turns fully liquid at 361 °F with no pasty range, so joints form quickly and evenly on boards, TVs, radios or DIY projects, reducing the risk of cold solder joints.
