Neil Metals, a reputable manufacturer and supplier of premium zirconium bars and rods with headquarters in Kolkata, India, provides top-notch solutions to industries requiring remarkable thermal stability and corrosion resistance. These bars and rods are specifically designed to satisfy the demanding specifications of nuclear power, chemical processing, and aerospace applications. Neil Metals guarantees products with dependable performance, high purity, and customised dimensions with a dedication to global standards and customer satisfaction. The business serves both domestic and foreign markets with prompt delivery and reliable quality by utilising years of metallurgical experience and a strong supply chain.
Typically, 99.2% or more zirconium is present in zirconium bars and rods, along with trace amounts of iron, oxygen, and hafnium (up to 4.5%). These parts provide outstanding resistance to corrosion, especially in hot and acidic conditions. Zirconium has a melting point of 1855°C, a tensile strength of approximately 330–580 MPa, and an elongation of 14–30%. It also has good formability, high ductility, and low neutron absorption. Because of these qualities, it is perfect for demanding applications where thermal resistance and chemical inertness are crucial.

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.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
