NIOBIUM - A material for innovations with great future potential
Niobium is a light gray metal with a gleaming white appearance on polished surfaces. It is characterized by a high melting point of 2,477°C and a density of 8.58g/cm³. Niobium can be easily formed, even at low temperatures. Niobium is ductile and occurs with tantalum in a natural ore. Like tantalum, niobium also features outstanding chemical and oxidation resistance.

Ferroniobium is mainly used for smelting high temperature (heat resistant) alloy, stainless steel and high strength low alloy steel. Niobium forms stable niobium carbide with carbon in stainless steel and heat resistant steel. It can prevent the grain growth at high temperature, refine the structure of steel, and improve the strength, toughness and creep properties of steel.
