KappTecZ™ Cadmium-Zinc-Silver solder is a high temperature, high strength solder that may be used on most metals, but works extremely well on Aluminum, Copper, and Stainless Steel. It has a high tolerance to vibration and stress, and good elongation for use on dissimilar metals. Above its liquidus of 600°F (316°C), this solder is extremely fluid and will penetrate the closest joints.

 

KappTecZ™ is used with a flux appropriate for the base metal, and its performance in application is similar to the more expensive Silver brazing alloys. The joints have good corrosion resistance, high electrical properties, and high shear and tensile strengths.

 

Applications
KappTecZ™ is a general purpose Silver alloy solder used for ferrous and non-ferrous joining where high strength is required at a comparatively low temperature. KappTecZ™ will solder all solderable metals including Aluminum, as well as Aluminum to Copper. It is often used to join Stainless Steel to Copper and Aluminum.

 

NOTE: Cadmium is a health hazard. See SDS for precautions and protections. Cadmium solders should NOT be used for food or potable water applications. Please see KappFree™ and/or KappZapp™ for Copper and Stainless Steel and/or KappAloy™ for Aluminum Food Safe and Potable Water Applications.

 

Properties

The following chart contains typical physical properties for KappTecZ™ solder joints. *Strength values are for an average joint on Copper-to-Copper, and are general guidelines when selecting solder for a particular application. Many factors, such as materials, temperature, and method of application determine the end result. Call Kapp Engineering Assistance to discuss your specific needs. We recommend testing appropriate alloys in your specific application to ensure suitability. Samples of Kapp alloys are always available upon request.
