96Sn/4Ag Lead-Free Solder

KappZapp4™ Tin-Silver solder is an NSF-certified lead-free solid wire solder containing 4% Silver, offering improved tensile strength, shear strength, elongation, and conductivity over KappZapp3.5™. It provides a wider workable range of 430-475°F (221-246°C) to allow users to manipulate parts, while the solder is hardening. In many cases, a stronger overall assembly exists after joining with KappZapp4™ Tin-Silver solder than with a higher temperature Silver brazing alloy process.

NSF Certified

NSF International certifies that this product complies with NSF/ANSI Standard 372: Drinking Water System Components – Lead Content. The product is also Certified to NSF/ANSI 61, Annex G, and conforms with Lead content requirements for “Lead-free” plumbing as defined by California, Vermont, Maryland, and Louisiana state laws and the U.S. Safe Drinking Water Act in effect as of January 4, 2014. Weighted average lead content < 0.25%; Solder and flux lead content < 0.20%. This alloy complies with the European RoHS and REACH directives. No lead, cadmium, or mercury is used in production.
