Kester 24-7068-6401 is a 1 lb spool of lead-free, organic, flux-cored solder wire that has a diameter of .020 inches. It is comprised of SN95.5AG04CU.5, or 95.5 percent tin, 4 percent silver, and .50 percent copper. Additionally, it has a #66 core size, and a 331 (organic, water soluble) flux type.
Kester 331 Organic Flux is a water soluble formula for use in flux-cored solder wire. This cored solder version of the popular 2331-ZX Neutral Organic Water Soluble Liquid Flux is more effective than rosin fluxes in soldering difficult metals. The same fast action and mild properties are exhibited with 331 Organic Flux as with the liquid 2331-ZX. The flux is more heat stable than most organic fluxes, resulting in minimal smoke and ordor. The residue can be completely removed with a simple water rinse.
Excellent solderability to a wide variety of metallizations
Easy residue removal in DI-water
Compatible with leaded and lead-free alloys
Classified as ORH1 per J-STD-004
This product meets the requirements of the RoHS (Restriction of Hazardous Substances) Directive, 2002/95/EC Article 4 for the stated banned substances. (Applies only if this core flux is combined with a lead free alloy)
