Rupal Metals, a prominent manufacturer and supplier located in Delhi, India, specializes in high-quality Nimonic Bars and Rods tailored for demanding applications in extreme conditions. Renowned for their exceptional high-temperature strength and resistance to oxidation, Nimonic alloys are perfect for critical engineering tasks. At Rupal Metals, we provide precision-engineered Nimonic bars and rods that adhere to international quality standards, earning the trust of clients in the aerospace, turbine, nuclear, and automotive sectors. Our commitment to reliability, performance, and customer satisfaction positions us as a go-to partner for specialized nickel-based alloy products in India and beyond.
Nimonic Bars and Rods are primarily composed of nickel-chromium-based alloys, with varying amounts of cobalt, titanium, aluminum, and molybdenum added based on the specific grade (like Nimonic 75, 80A, 90). These additional elements boost high-temperature strength, creep resistance, and oxidation stability. Typical mechanical properties include tensile strength surpassing 800 MPa, yield strength around 500 MPa, and impressive creep resistance at temperatures exceeding 800°C. Nimonic alloys maintain their structural integrity under thermal stress and cyclic loading, providing high fatigue resistance, excellent weldability, and a long service life even in harsh operating conditions.

Nimonic rods can be susceptible to galvanic corrosion when in contact with more electropositive metals, especially in the presence of an electrolyte. Proper insulation or coating can help mitigate this risk.
Nimonic bars are available in various sizes, ranging from small diameters (6mm) to larger ones (up to 200mm). Common finishes include hot rolled, cold drawn, and polished.
Yes, Nimonic alloys, including Nimonic 75 and 80A, can be welded. However, proper welding procedures and pre- and post-weld heat treatment are essential to avoid cracking and ensure strength.
Nimonic Bars and Rods find extensive use in high-temperature and high-stress environments where traditional materials fall short. They are commonly used in components for gas turbines, jet engines, exhaust systems, nuclear reactors, and heat treatment equipment. These bars are also utilized in aerospace fasteners, springs, valves, combustion chambers, and high-performance automotive parts. In the power generation sector, Nimonic rods are preferred for their reliability in the face of thermal fatigue and corrosive environments. Their remarkable resistance to oxidation, corrosion, and mechanical wear makes them a top choice for 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.
