Product Introduction
Zirconium bar is a high-performance corrosion-resistant metal product widely used in chemical processing, nuclear industry, aerospace, medical equipment, and marine engineering.
Zirconium (Zr) is a silvery metal with a density of approximately 6.52 g/cm³ and a melting point of 1855 °C. Due to its extremely low neutron absorption cross-section and excellent corrosion resistance, zirconium is an important material in nuclear reactors and highly corrosive chemical environments.
Zirconium alloys such as R60702 and R60705 offer improved strength and corrosion resistance through alloying elements including niobium and hafnium.
