Zirconium Bars and Rods are primarily made from zirconium metal, with small amounts of hafnium and other trace elements added to boost corrosion resistance and mechanical performance. On the mechanical side, zirconium boasts a tensile strength between 380 and 550 MPa, a yield strength of 200–380 MPa, and a hardness rating of 90–160 HB. It’s highly ductile, has great thermal conductivity, and maintains its shape even at high temperatures. These characteristics make zirconium bars and rods ideal for applications that demand resistance to chemical attacks, high strength, and long-lasting reliability in challenging environments.

Yes, Zirconium bars can be welded. It requires specialized techniques such as gas tungsten arc welding (GTAW) to ensure good weld quality, as it is highly reactive at elevated temperatures.
To maintain zirconium rods, keep them clean and free of contaminants. Store in a dry, cool environment. Avoid mechanical damage and ensure proper handling to prevent oxidation or corrosion.
Zirconium bars are generally resistant to galvanic corrosion due to their high corrosion resistance properties. However, when paired with more reactive metals, galvanic corrosion may still occur.
Zirconium Bars and Rods find extensive use in industries where corrosion resistance and high-temperature performance are vital. They play a key role in chemical processing equipment, heat exchangers, nuclear reactors, and marine components. Their biocompatibility also makes them a great fit for medical devices and implants. Plus, zirconium’s resistance to oxidation and impressive mechanical properties allow it to be utilized in aerospace, defense, and electronic applications. Starc Metals’ zirconium products guarantee consistent quality, empowering manufacturers and engineers to create durable, precise, and high-performance components that thrive in demanding operational conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
