DIALLOY® 824 Tin-Zinc-Electrolyte

Environmentally friendly, cyanide-free SnZn process as a reliable alternative to cadmium for extreme conditions

DIALLOY® 824 represents the latest development in modern, cyanide-free SnZn coating technology. The alkaline process meets the industry's increasing demands for safe, sustainable, and high-performance manufacturing processes and is suitable for barrel and rack operation.

The silk-matt, silver-colored coating was specially developed for maximum loads and is a fully- fledged replacement for cadmium, even under extreme operating conditions.

Thanks to its non-reflective surface, the coating is particularly suitable for applications in aerospace, automotive, and electrical engineering. DIALLOY® 824 combines reliable performance with environmental compatibility without compromising on safety, quality, or durability.
