Does nickel turn black?
Yes, nickel can turn black. This is usually due to oxidation. When nickel is exposed to the air, the oxygen in the air will react with the metal’s surface, creating an oxide layer. The oxide layer gives nickel a black color.
Additionally, nickel is frequently alloyed with other metals to improve its strength and corrosion resistance. These alloys may sometimes darken the alloy’s color, making it appear black. Another common reason that nickel may turn black is due to contact with sulfur containing compounds.
This chemical reaction will cause a black sulfide layer on the nickel which can be difficult to remove.
