Kester 24-6337-0061 SN63PB37 66 Core 44 Flux Solder Wire .062 Dia

Kester 24-6337-0061 is a 1 lb spool of of leaded, RA, cored-flux solder wire that is .062 inches in diameter. It is comprised of SN63PB37, or 63 percent tin and 37 percent lead. Additionally, it has a 66 core size and a 44 flux (RA) 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
