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.
Tariku Metals’ Zirconium Bars and Rods find a wide range of uses across various industrial sectors. In the nuclear industry, they are utilized as cladding material for fuel rods due to their low neutron-capture cross-section. Their corrosion resistance makes zirconium an excellent choice for heat exchangers, pumps, and reactor vessels in chemical processing. The aerospace and marine sectors rely on it for high-performance components that must withstand extreme conditions. Additionally, zirconium rods are employed in biomedical implants, surgical instruments, and electronics, thanks to their strength, biocompatibility, and resistance to oxidation and chemical attack.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
