4890-18G

4890-18G is a Sn60/Pb40 RA solder wire. This solder wire is electronics grade and the 60 40 rosin core uses a tin-to-lead alloy ratio with an RA-like flux core. It melts at slightly higher temperatures and over a wider temperature range than 63/37 solder. This results in robust and reliable joints that are highly resistant to whisker formation. It achieves a consistent solder and flux percentage due 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.
