Kester 24-6040-6411 SN60PB40 66 Core 331 Flux Solder Wire .062

Kester 24-6040-6411 is a 1 lb spool of leaded wire solder that is .062 inches in diameter. It is comprised of SN60PB40 or, 60 percent tin and 40 percent lead. Additionally, it has a core size of 66 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 is 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 odor. The residue can be completely removed with a simple water rinse. Performance Characteristics:Excellent solderability to a wide variety of metallizationsEasy residue removal in DI waterCompatible with leaded and lead-free alloysClassified as ORH1 per J-STD-004
