KappZapp3.5™ Tin-Silver solder is a NSF certified Lead-free eutectic solder that provides a strong and ductile joint with a high tolerance to vibration and stress on Copper, Brass, and Stainless Steel. In many cases, a stronger overall assembly exists after joining with KappZapp3.5™ Tin-Silver solder than with higher cost higher temperature Silver brazing alloys. The low eutectic melting temperature of 430°F (221°C) prevents loss of properties and minimizes distortion on thin wires, tabs, and sheets.
NSF International certifies that this product complies with NSF/ANSI Standard 372: Drinking Water System Components – Lead Content. Product 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 used in production.
