KappZapp™ Silver Solders for Electrical/Electronic Copper and Brass / SOLID WIRE Silver Solders for Electrical/Electronic Copper and Brass
KappZapp™ solid wire solders produce strong and ductile joints on Copper wires and tabs. The resulting joints have high tolerance to vibration and stress, with tensile strengths to 15,500 psi on Copper. KappZapp7™ - 93% Tin / 7% Silver is the best Copper-to-Copper solder available, with high strength, ductility and corrosion resistance.
KappZapp3.5™ is the most popular of the low temperature Silver bearing solders. It melts completely at just 430°F (221°C). This minimizes the heat applied to your sensitive electronic parts and minimizes distortion of thin wire or tabs. Learn More
KappZapp4™ contains 4% Silver (Ag), and is often preferred for hand soldering Copper wires and tabs. It has a wider slushy or plastic range (430°F-475°F and 221°C - 246°C) to allow users to manipulate parts while the solder joint is cooling and hardening. Learn More
KappZapp7™ is an audio industry standard for vehicle and home theater speaker installations. Its 7% Silver content requires a higher temperature range, but yields superior strength and vibration resistance. Learn More
Flux designed specifically to work with KappZapp3.5™ and KappZapp4™ Silver solders to remove the oxide layer on Copper to allow a strong metallic bond between the solder and the base metal. Its active range is 350°F - 500°F (176°C - 260°C). Learn More
Flux designed specifically to work with KappZapp7™ 7.0% Silver solder to remove the oxide layer on Copper to allow a strong metallic bond between the solder and the base metal. Its active range is 500°F - 750°F (260°C - 390°C). Learn More
