Kester 24-6337-0007 SN63PB37 66 Core 44 Flux Wire Solder .015 Dia

Kester 24-6337-0007 is a 1lb spool of leaded, flux-cored, RA wire solder that has a .015 inch diameter. it is comprised of SN63PB37, or 63 percent tin and 37 percent lead. 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
