MG Chemicals 4901-454G SN99 No Clean Solder Wire 2.2% Flux Core 0.81mm (0.032 in) 454 G (1 LB) 21AWG Spool

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.

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).
