ferroniobium 

Usage:

Niobium is mainly used in the steel industry, and its most important use is as a microalloying element to produce low alloy high-strength tempered steel. Adding niobium to steel products can greatly improve their strength, toughness, and welding performance. In addition, niobium is widely used in industries such as high-temperature alloys, casting, amorphous and magnetic materials, superconducting materials, fine ceramics, and optical glass.
