4885-227G, 21AWG ROSIN ACTIVATED FLUX CORE SOLDER WIRE, Sn63/Pb37. 227g SPOOL
MRO Part # 4885-227G
This is a 21 AWG rosin-activated flux core solder for electronics. Sn63/Pb37 eutectic alloy 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 connections that are highly resistant to whisker formation and cold solder joints.
