Kester 24-6337-0053 SN63PB37 66 Core 44 Flux Solder Wire .050 Dia

Kester 24-6337-0053 is a 1 lb spool of leaded, RMA, cored-flux solder wire that has a diameter of .050 inches. It is comprised of SN63PB37, or 63 percent lead and 37 percent tin. Additionally, it has a 66 core size and a 44 (RA) flux type. Kester 44 Rosin Flux is an activated rosin formula for use in flux-cored solder wire. Kester 44 Rosin Flux has virtually dominated the field of activated rosin core solders for well over four decades. An outstanding performance feature of this flux is the "instant-action" wetting behavior. The high mobility and fast-spreading action of this flux results in more reliable production line soldering. Performance Characteristics:High activity RA formulationExcellent solderability to a wide variety of metallizationsIndustry standard RA cored wire for decadesClassified as ROM1 per J-STD-004
