The MG Chemicals No-Clean Solder Wire 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.
