NbW

NbW is a niobium-tungsten alloy combining two refractory metals known for exceptional high-temperature stability and strength. This material is employed in extreme-environment applications where conventional superalloys reach their limits, particularly in aerospace propulsion systems, nuclear reactor components, and high-temperature structural applications where resistance to thermal cycling and oxidation is critical. Engineers select NbW-based compositions when operating temperatures exceed the capability of nickel-based superalloys and when weight efficiency combined with creep resistance becomes essential, though such alloys typically require specialized processing and protective coatings due to oxidation susceptibility at elevated temperatures.
