Tin-Zinc-Cadmium Solder
KappRad™ is a Tin-Zinc-Cadmium multipurpose solder developed specifically to join and repair Aluminum and Aluminum/Copper radiators as well as heat exchangers. Its lower melting point makes delicate repair work easier.
KappRad™ forms very strong joints on most metals, including
- Aluminum
- Stainless Steel
- White Metal
- Pewter
- Copper
- Brass
- Galvanized Steel
In addition, it can be plated with Chrome, Nickel, or Copper. In most cases, the repair is stronger than the original metal.
Applications & Features
- Join and repair:
- Aluminum and Aluminum/Copper radiators
- Heat exchanges
- Use any heat source :
- Oxy-acetylene torch
- Natural gas torch
- Propane torch
- Heat gun
- Soldering iron
- Paired with Kapp Golden™ Flux
This alloy is NOT recommended for food or potable water applications. Please see KappFree™ and/or KappZapp™ for Food Save and Potable Water Applications.
