KappTec™ Cadmium-Silver solder is a high temperature, high strength, general purpose solder for all solderable metals except Aluminum. It is highly recommended for Stainless Steel to Stainless Steel and Stainless Steel to Copper soldering. This alloy is outstanding in high vibration and high stress situations. Its high electrical conductivity versus other solders makes it an excellent choice for electrical applications.
Applications
- Highly recommended for Stainless Steel and Copper soldering
- Outstanding in high vibration and high stress applications
- High electrical conductivity versus other solders makes it an excellent choice for electrical applications
- Particularly helpful with large parts that require more heat
- Performance in application is similar to the more expensive Silver brazing alloys
- This alloy is NOT recommended for food or potable water applications. Please see KappFree™ and/or KappZapp™ for NSF compliant Food Safe and Potable Water Application.
KappTec™ is used in applications where alloys melting higher than soft solders are required, but the cost and strength of Silver-brazing alloys are not necessary. Above its solidus of 640°F (338°C), this solder is extremely fluid and will penetrate the closest joints. KappTec™ is used extensively in light bulbs, light fixtures, and other high vibration, high stress electronic applications.
Best Use & Features
- Greater bond strength and consistency are accomplished by pre-tinning the parts with KappTec™ before jigging into final positions
- Pre-tinning helps avoid overheating the flux in the final joining process, resulting in better flow and a stronger joint
- The joints have good corrosion resistance, high electrical properties, high shear, and high tensile strengths
- Paired with Kapp CopperBond™ Flux
Properties
The following chart represents the physical properties of KappTec™ solders. Many factors, such as materials, temperature, and method of application determine the solder joint strength and characteristics. Call Kapp Alloy 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.
