Lead-free soft solder for soldering of rolled blank and coated zinc and zinc alloys (titan zinc) in roofing. SnZn-801 distinguishes itself in its very good flow and wetting characteristics. A professional executed soldering seam with this solder is permanently watertight and shows a high fatigue strength almost close to the base material. With its low melting point it is perfectly adjusted to zinc and provides a big process window.
