Niobium
|
Niobium is a nickel-free inert metal. It is very resistant to corrosion and other reactions, and is used in medical implants. Niobium is not plated or painted, so it will not flake or chip. It is anodized, meaning it is colored by dipping it into an electrically charged bath.
Most people who are sensitive to metal can comfortably wear niobium. For this reason, I use niobium ear wires for earrings with copper components. |
