The major element in the Zirconium Bar and Rod (Zr) in the purity level of 99.5 to 99.9%. Impurities include Fe ≤ 0.15%, Cr ≤ 0.1%, Ni ≤ 0.1%, etc., and some traces of O and C. The metal possesses an excellent property for corrosion, which is ideal in aggressive surroundings like acids. Its mechanical properties are high tensile strength between 350 MPa and 900 MPa, good ductility, and excellent resistance to fatigue. In addition, it retains strength at elevated temperatures and has a low thermal neutron absorption cross-section.

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 bar and rod alloys are widely used across various industries due to their high strength and outstanding corrosion resistance. One of their most critical applications is in nuclear reactors, where zirconium serves as fuel cladding thanks to its low thermal neutron absorption properties. In the chemical industry, zirconium’s excellent resistance to acids and alkalis makes it ideal for fabricating reactors, piping systems, and heat exchangers. In the aerospace sector, its ability to withstand high temperatures and extreme environments makes it suitable for critical structural components. Additionally, zirconium is valued in the medical field for use in implants, as it is biocompatible, highly durable, and resistant to corrosion, resulting in minimal risk of rejection. These combined properties make zirconium a versatile and reliable material across a broad spectrum of demanding applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
