Niobium Zirconium Damascus is a composition of different grades of alloy layers similar to (titanium damascus) but instead of titanium this consists of the two alloys Niobium and Zirconium. The technical name for Niobium Zirconium Damascus is NbZr which is the elements Niobium and Zirconium from the periodic table of the elements. As we now know in titanium damascus the colors have a standard coloration of vibrant colors it goes through while anodizing. But Niobium and Zirconium are different and unique in that they go through a slight color range and then quickly to dark gray and even black depending on the finish to the surface like Titanium. Zirconium has a higher strength color crystal than its partner titanium and Niobium even stronger which makes it the most scratch resistant alloy composition that JBlunt Designs carries. NbZr damascus is also extremely hard to find, I am aware of only one forger in the world that has been successful at making it and we carry it!
