Neil Metals, based in Kolkata, India, has earned a solid reputation as a reliable manufacturer and supplier of top-notch Nickel Alloy Hollow Bars. These bars serve a variety of industries, including chemical processing, marine, aerospace, and oil & gas. Known for their precision-engineered products that adhere to strict global standards, Neil Metals offers Nickel Alloy Hollow Bars that boast impressive corrosion resistance, thermal stability, and mechanical strength. With state-of-the-art infrastructure, tailored solutions, and prompt delivery, Neil Metals is dedicated to fulfilling the intricate needs of clients who require durable, high-performance materials for critical applications in harsh and high-temperature settings.
Nickel Alloy Hollow Bars primarily consist of nickel (usually 60–70%) along with elements like chromium, molybdenum, iron, and copper, depending on the specific alloy grade. These alloys are known for their remarkable resistance to high-temperature oxidation, stress corrosion cracking, and various acidic and alkaline environments. Their mechanical properties include tensile strength ranging from 500 to 850 MPa and yield strength between 200 to 500 MPa. Additionally, nickel alloys offer high toughness, fatigue resistance, and good weldability. Their stable structure and corrosion resistance make them perfect for challenging conditions involving pressure, heat, and aggressive chemicals.

Nickel Alloy Hollow Bars find extensive use in industries that operate in highly corrosive or high-temperature environments. In the chemical and petrochemical sectors, they are utilized in reactors, heat exchangers, and piping systems that handle acidic or caustic substances. The marine industry employs them in seawater systems, condensers, and underwater components due to their resistance to saltwater corrosion. In aerospace and power generation, they are essential for turbine parts, engine components, and heat-resistant fittings. Their hollow design makes them ideal for machining into bushings, sleeves, and precision-engineered components where strength is crucial.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
