4880-4888 – Sn63/Pb37 RA Solder Wire

4880–4888 Sn63/Pb37 RA Solder Wire is electronics grade solder wire. This 63/37 solder uses the eutectic tin-to-lead alloy ratio, which is complemented with an RA-like flux core. This tin-lead solder wire meets J-STD-004B, ASTM B 32, and exceeds J-STD-006C specifications. It is one of the easiest solders to work with because it offers a low-melting temperature with a sharp melting/solidification point, which results in robust and reliable joints that are highly resistant to whisker formation.

  • Eutectic alloy (liquidus = solidus temperature)
  • Alloy exceeds J-STD-006C and meets ASTM B 32 purity requirements
  • Flux meets J-STD-004B
  • Rosin-activated flux
  • Fast wetting
  • Fast flowing
  • Non-corrosive residue
  • Non-conductive residue

This 63/37 rosin core solder achieves a consistent solder and flux percentage thanks to our state-of-the-art extrusion wire-drawing machine, which continuously monitors the wire to prevent voids and ensure consistency, providing a top-grade solder wire.

For Sn63/Pb37 no-clean solder wire try 4860-4867. We also offer Sn60/Pb40 no-clean solder wire and Sn60/Pb40 RA Solder Wire.

For lead-free solder wire try 4900-4917, 4901, or 49500WS.
