Kapp Tin-Silver Solder Formulations
Kapp Alloy & Wire, Inc. manufactures all the ASTM and SAC standard formulations of Tin-Silver and Tin-Silver-Copper solders. These include, but are not limited to:
KappZapp™ Tin-Silver solders produce strong, ductile joints on Copper, Brass, and Stainless Steel. The resulting joints have a high tolerance to vibration and stress, with tensile strengths to 33,000 psi on Stainless Steel. The entire line of KappZapp™ solders is NSF® certified Lead-Free for potable water and plumbing applications.
KappFree™ solders are NSF compliant Lead/Cadmium-free formulations designed specifically to replace Lead solders in Copper and Stainless Steel plumbing as well as in electrical/electronic applications. With less Silver, these lower cost solders provide less joint strength, vibration resistance, and thermal cycle fatigue resistance compared to KappZapp™ solders.
KappSAC305™ 96.5%Tin-3.0%Silver-0.5%Copper solder is a standard Lead-free formulation designed for circuit board and electronic soldering. Kapp Alloy manufactures all of the various SAC alloys of Tin-Silver-Copper. Call for a quotation and availability of in stock items.
