FF Rainbow-Zr is Titanium-Zirconium damascus composite. Zirconium (Zr) is a highly corrosion resistant element. Because of it’s unique properities is used in space, aeronautic and medical industries. Zirconium turns black in the anodization colour spectrum. You can reach different colour schema by electro-chemical or heat oxidation, each piece of produced material can be coloured differently. Our composites are highly corrosion resistant even when there is a long-time contact with human skin or exposed to the most commonly available acids. Suitable for knife handle, knife hardware, jewelry applications, watchmaking or pen making. Marking: "FF Rainbow Zr", hashtags: #BlackFuturon #RainbowFuturon.
