Nickel-Niobium/Nickel-Columbium (NiNb) Master Alloy

KBM Affilips supplies a complete range of alloys, including the nickel-niobium, or nickel-columbium, (NiNb) master alloy, for use in the nickel industry.

The nickel-niobium or nickel-columbium (NiNb) master alloy supplied by KBM Affilips is used in the production of special steels, stainless steels and superalloys for solid solution strengthening, precipitation hardening, deoxidation, desulphurization and many other processes.

NiNb Master Alloys

The table below lists the type of NiNb master alloy supplied by KBM Affilips:

Alloy Form Composition
NiNb65 Lumps of defined size; lump shape is usually alloy specific 65% Nb balance Ni


The nickel-niobium 65% master alloy is mainly used in the production of special nickel steels and nickel-based super alloys. Niobium enhances the mechanical properties, creep resistance and weldability of steels and super alloys.

The melting point of niobium and base metal varies considerably and hence it is difficult to add pure niobium to the bath. In contrast, nickel-niobium dissolves very easily as its melting temperature is similar to or lower than the standard operating temperature.

This master alloy is also being utilized for adding niobium to copper-nickel alloys to enhance the mechanical properties in cryogenic applications.

Applications of NiNb Master Alloys

  • NiNb is used for improving the mechanical properties of nickel-based steels, CuNi alloys and super alloys.
