Overview

Niobium, also known as Columbium, is a ductile metal that is most commonly used as a strong structural steel alloy. It’s a structurally sound metal with a high melting point and high resistance to corrosion. It is commonly combined with steel, nickel, cobalt, iron and other metals to create a strong, resistant alloy. As well as being very stable under extreme temperatures. Material data provided by Eagle Alloys.
