NP Solder Sticks Sn63/Pb37 are premium eutectic solder alloys designed for high-performance wave soldering, dip soldering, and solder pot applications. Manufactured using high-purity virgin tin and lead, they provide excellent wetting characteristics, smooth solder flow, minimal dross formation, and reliable metallurgical joints for consistent production quality.
The eutectic composition eliminates the plastic range, allowing the alloy to transition directly from liquid to solid, resulting in faster solidification and reduced risk of cold solder joints.
