Physical and Chemical Properties
Monel alloys can be finished as a white silver with a high polish, as a pewter-like matte gray or with a thin black oxide layer. Indoors, it oxidizes to form a clear layer, but can form a gray-green film outdoors.
Nickel metal and alloys are skin and respiratory sensitizers, as well as carcinogens.
