Kester Solder 24-6337-0027 Sn63Pb37 Solder Wire — 1 lb Spool, 183°C

Overview

Kester 24-6337-0027 solder wire comes on a practical one-pound spool, ideal for electronics projects ranging from hobby builds to small repairs. The alloy is Sn63Pb37, signaling a blend of 63% tin and 37% lead that delivers dependable wetting and solid joint formation when heated to common electronics temperatures. The melting point is around 183 degrees Celsius, offering a balanced profile that supports controlled heat input without excessive component stress.

Real-world performance matters in daily work. The 1 lb spool provides ample material for longer sessions, reducing interruptions for restocking. The wire’s consistent diameter helps maintain steady flow, contributing to clean, bright joints on component leads and copper traces. Tin content supports reliable surface wetting, while lead adds filling characteristics that many makers rely on for durable connections across through-hole and some surface-mount tasks.
