DIALLOY® 822 Tin-Zinc-Electrolyte
DIALLOY® 822 Tin-Zinc-Electrolyte
Coatings with low porosity for technical applications
DIALLOY® 822 is an alkaline cyanide electrolyte for the deposition of a tin-zinc alloy in barrel or rack operation.
The alloy composition is on average 80 % Sn and 20 % Zn, whereby other Sn/Zn alloy ratios can also be deposited by varying the working parameters.
The electrolyte is suitable for the deposition of silk-matt alloy layers.
Alloy layers deposited of DIALLOY® 822 are mainly used in technical applications. They are suitable as an anti-corrosion coating for iron and iron alloys, but also as corrosion protection in combination with light metals such as aluminum. Corrosion resistance can be further increased by suitable post-treatment (passivation, sealing).
Moreover, the layers have a good solderability and weldability.
