Niobium is a shiny, white, soft, ductile and paramagnetic metal, which takes on a bluish tinge when exposed to air at room temperatures for extended periods.  It has a low density in comparison to other refractory metals, and it is corrosion resistant, exhibits superconductivity properties, and forms dielectric oxide layers. These properties, especially the superconductivity, are strongly dependent on the purity of the niobium metal. When very pure, it is comparatively soft and ductile, but impurities make it harder.

Niobium- Titanium Alloy ( TiNb alloy, NiTi alloy)
Keywords: TiNb alloy, NiTi alloy, superconducting, ASTM B884
Niobium-titanium (NbTi) is an alloy of niobium and 44% ~ 48% titanium, which is used industrially for superconducting applications.

Nb-1Zr (Niobium-1%Zirconium)
Keywords: R04251, R04261
Alloying niobium with 1% zirconium greatly improved the creep strength over the soft pure niobium and decreases slightly its elongation. The increased strength is very advantageous especially at temperatures above 600 °C.

Due to its low thermal nuclear capture cross-section properties, the Nb-1Zr alloy has been closely associated with the nuclear industry, which requires specified elevated temperature strength in the range of 1800° F to 2200° F.

Nb-5Zr (Niobium-5%Zirconium Alloy)

Nb-10Zr (Niobium-10%Zirconium alloy)

Nb-Hf-Ti Alloy (Nb+10%Hf+1%Ti)

NbC (Nb2C, Niobium Carbide)
Niobium carbide (NbC and Nb2C) is an extremely hard refractory ceramic material, extensively used in tool bits for cutting tools and as refractory coatings in nuclear reactors. It has the appearance of a brown-gray metallic powder with purple lustre and is highly corrosion resistant.
