Will nickel rust?
Nickel does not rust. Rusting is the property of iron and its alloys due to which they oxidize to form a layer of loose powdery iron oxide which makes the object brittle and fragile. Nickel is highly resistant to corrosion. It withstands a wide range of temperatures, extremely humid conditions, and harsh chemicals.
