Niobium (Nb) Plate Mechanical Property

Niobium is gray, like all other metals. However, by applying a pacifying oxide layer, it will gleam in a beautiful array of colors. Niobium does not just look pretty. Like tantalum, it's resistant to many chemicals and can be formed easily even at low temperatures.
