KappAloy20™ Tin-Zinc spray wire combines the advantages of the low melting temperature of Tin, with the corrosion resistance of Zinc. This solder displays higher tensile strength and temperature tolerances compared to KappAloy9™ and KappAloy15™.

 

Applications

KappAloy20™ is used extensively in spray wire form to coat the ends of capacitors and other electronic parts to provide a hermetic seal, EMF/EMI protection, and corrosion resistance. Like Tin surfaces, the coatings are easily solderable. As with Zinc, the coating has substantial oxidation resistance.

1 Depends on air pressure, standoff, nozzle cap, and target size.

2 6" standoff, 40 psi - 8830, depends on air pressure - fine with high psi, average with medium psi, and

rough with low psi.

3 Higher air pressures, smaller wire (1/16), and lower amperage with red nozzle cap gives smallest

diameter
