Niobium is used as an additive in nickel-, iron- or cobalt-based superalloys. It not only has a high melting point of 2468°C, but is also resistant to corrosion and oxidation.

For this reason, H.C. Starck's nickel niobium is a preferred component in superalloys used for parts that must withstand high temperatures. Moreover, nickel niobium compensates for high tension stresses as well as shocks caused by vibration and impact.

Nickel Niobium

Refining steels with superalloys that contain niobium ensures improved machine performance and fuel combustion, lower machine maintenance costs and greater safety. Nickel niobium slows the aging process of a material and prevents crack formation under thermal stress.

Niobium based superalloys find their application in components for aircraft turbines, gas turbines and for assembly parts for rockets.

Thanks to its particularly high resistance to corrosion and oxidation, nickel niobium is often used in superalloys for demanding applications in chemical facility construction. It is indispensable as a component in pipeline constructions and as an additive to applied steels and welding wire for parts that are subject to a corrosive environment.

The nickel niobium produced by H.C. Starck has a niobium content of 58%-65% and is offered as a superalloy additive.

We use recycling both to ensure a supply of raw materials and to remain independent from fluctuations in supply and price. We are able to reclaim niobium from almost any type of scrap with a niobium content of 1 to 99%. Based on our "closed-loop offer", we accept used, recyclable products that contain niobium from our customers and reprocess them to produce high-performance niobium products.
