Metal Deposition Solutions

As demands for sustainability and process reliability continue to rise, new coating technologies are increasingly coming into focus. One such technology is DIALLOY® 824, the latest advancement in modern, cyanide-free SnZn coating technology. This alkaline process meets the industry’s growing demands for safe, sustainable, and high-performance manufacturing processes and is suitable for both barrel and rack operations.

The satin-matt, silver-colored coating was specifically developed for the most demanding applications and proves itself as a fully-fledged substitute for cadmium even under extreme operating conditions.

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