A coated article is provided so as to include a coating (e.g., low-E coating, or the like) having at least one layer of or including niobium chromium (NbCr). The NbCr layer may be nitrided. The NbCr inclusive layer (e.g., NbCrNx) may be provided as any suitable layer of the multi-layer coating, but in certain example instances may be used as a contact layer adjacent to an infrared (IR) reflecting layer. Coated articles herein may be used in the context of insulating glass (IG) window units, laminated windows, architectural or residential monolithic window units, vehicle window units, and/or the like.
