DIALLOY® 822 Tin-Zinc-Electrolyte

Matt gray cadmium substitute for the highest technical demands, even under extreme operating conditions

DIALLOY® 822 is an alkaline cyanide electrolyte for the deposition of an alloy of tin and zinc in barrel or rack operations.

The alloy composition averages 80% Sn and 20% Zn, although other Sn/Zn alloy ratios can also be deposited by varying the operating parameters.

The process offers outstanding properties such as excellent soldering and welding abilities, high conductivity (< 5 mOhm), low porosity, and reliable protection on iron, iron alloys, and light metals such as aluminum. It offers excellent corrosion resistance (500 hours salt spray test) and meets the highest environmental standards: chrome VI-free, RoHS and REACH compliant.

The matt gray, non-reflective surface is particularly suitable for aerospace, automotive and electrical engineering applications and offers a fully-fledged, environmentally friendly alternative to cadmium for demanding conditions.
