Q:Is the coating on anti-fingerprint sheet metal zinc or nickel?

The coating on anti-fingerprint sheet metal is primarily zinc; however, zinc-nickel alloy coatings are also found in actual products. In these cases, nickel is added as an alloying element rather than forming a pure nickel coating.

Anti-fingerprint sheet metal is essentially a composite material created by applying an anti-fingerprint film (an organic or inorganic coating) over a galvanized steel substrate (produced via either electro-galvanizing or hot-dip galvanizing). Therefore, the base coating is zinc.

Specifically, there are two main types of coatings:

Pure zinc coating (Z): This is the most traditional and common type. Continuous electro-galvanizing lines produce a coating composed of pure zinc, free from trace elements that could adversely affect painting performance.

Zinc-nickel alloy coating (ZN): This is a more advanced coating. Produced via electroplating, the coating consists of a zinc-nickel alloy containing approximately 8% to 15% nickel by weight, with the remainder being zinc.
