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 will not flake or chip. It is anodized, meaning it is colored by dipping it into an electrically charged "bath." Because it contains no nickel, lead, or other additives, most people with metal allergies can safely wear niobium.
