DESCRIPTION

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.Sn99 solder is a great lead-free alternative to leaded solders, and is considered one of the best solder wires for electronics. It is a suitable and less costly replacement for SAC305.4901 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).
