Titanium-zirconium alloy rod

I. Product Introduction
Ti-Zr Alloy Bar is a rod-shaped metallic material made from titanium as the base material, with the addition of zirconium (usually 2%~20%), through vacuum melting, forging, rolling, and precision machining. It combines the lightweight and high strength of titanium with the excellent corrosion resistance of zirconium, making it a key structural/functional material in high-end equipment applications.
