Kester 24-6040-0018 Solder 60/40 .025
24-6040-0018 KESTER 44 ROSIN CORE SOLDER – 16 oz.
Sn60Pb40 (60% Tin / 40% Lead) alloy, .025″ wire diameter, #44 fully activated rosin flux, and #66 flux core size. Kester Formula #44 is a high activity RA flux, specifically designed for use in flux-cored solder wire. An outstanding performance feature of this flux is its “instant-action” wetting behavior, even on nickel surfaces. The high mobility and fast-spreading action of this flux results in more reliable production line soldering. Although #44 is an RA-based material, the residues are noncorrosive if not cleaned. Kester #44 is classified as ROM1 per J-STD-004
