4901 – Sn99 No-Clean Solder Wire
4901 Sn99 No-Clean Solder Wire is a solder wire for electronics. It uses a high-purity eutectic Sn99.3/Cu0.7 alloy, complemented by a no-clean, synthetically refined, spatter-proof resin flux core. 4901 solder meets J-STD-004B, ASTM B 32, and exceeds J-STD-006C specifications.
- Eutectic alloy (liquidus = solidus temperature)
- Alloy exceeds J-STD-006C and meets ASTM B 32 purity requirements
- Flux meets J-STD-004B
- Resin spreads like rosin-activated flux
- Virtually non-spattering
- Non-corrosive
- Non-conductive
- Halide-free
- Suitable for Use in Food Facilities as a Non-Food Chemical—Canadian and NFS recognition letters available on request
Full Product Details
4901 lead-free 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 a no-clean SAC305 solder wire try 4900. For a water soluble Sn100e solder wire try 49500WS.
We also offer Sn60/Pb40 leaded solder wire (no-clean and RA flux core) and Sn63/Pb37 leaded solder wire (no-clean and RA-like flux core).
