Kester 24-6337-0027 Sn63Pb37 Solder Wire, 1 lb Spool (.031" Diameter) Rosin

Kester part number 24-6337-0027 is a professional grade solder wire featuring a Sn63Pb37 eutectic alloy with 3.3% 44 Rosin Activated flux core. The 0.031 inch diameter makes it ideal for PCB assembly, electronics rework, through hole soldering, and precision repair work where medium sized joints require reliable flow and consistent wetting. This tin lead composition melts at 183°C, the eutectic point where both phases solidify simultaneously, ensuring fast cooling and minimal joint stress on delicate components. Kester's rosin flux delivers excellent wetting characteristics for professional electronics work, though residue must be cleaned after use for best results.

Key Features:

Alloy Composition: Sn63Pb37 (63% Tin, 37% Lead)
Diameter: .031" (0.8 mm)
Weight: 1 lb (approximately 454 grams)
Package Type: Spool (SPL)
Flux Core: 3.3% 44 Rosin Activated Flux
Melting Point: 183° C 361° F
Eutectic solder melts and solidifies at the same temperature.

.031" Diameter suitable for medium sized soldering jobs. Rosin Flux must be cleaned after use.

.010" (0.25 mm)	Ultra fine sized diameter useful for precision soldering and micro electronics.
.015" (0.4 mm)	Very fine sized diameter useful for precision soldering and jobs requiring small amounts of solder.
.020" (0.5 mm)	Fine sized diameter used for through hole and and surface mount work. Delivers a Controlled amount of solder.
.025" (0.6 mm)	Ideal for standard circuit board components where precision is needed but not ultra-fine work.
.031" (0.8 mm)	Ideal for fixing circuit boards, replacing components, and general rework. Popular for Arduino, Raspberry Pi, and DIY projects. It's a versatile diameter, often called the "sweet spot" for electronics.
.040" (1.0 mm)	Perfect for surface-mount devices (SMDs) and medium components where precision is key but more solder is needed.
.050" (1.27 mm)	Used for various tasks where a balance of flow and control is required, like general electrical repairs.
.062" (1.5 mm)	medium-thickness wire ideal for general electronics, larger through-hole components, appliance repair, automotive work, and crafts like stained glass
.093" (2.36 mm)	versatile, medium-to-thick wire used for general and heavier-duty electrical, electronics, automotive, and HVAC repairs/manufacturing.
