Zinc-Manganese Alloy Electroplated Steel for Automotive Body 860268

Zinc-manganese alloy electroplated has been developed for automotive body panel applications. The product is manufactured on a conventional electrogalvanizing line using an electrolyte containing zinc sulfate, manganese sulfate and sodium citrate. Electroplated steel with an alloy content of 30-50% manganese exhibits excellent corrosion resistance both as-produced and after painting. Zinc-manganese coatings also show good workability and voidability. Accordingly, this product is suitable for both unexposed parts and the interior surfaces of exposed parts. Finally, zinc-manganese electroplated steel displays good wet adhesion and anti-cratering characteristics so that the product can also be used for exposed applications as automotive body panels.
