Mourad Metals, located in Tunis, Tunisia, stands out as a top manufacturer and supplier of high-performance Nimonic bars and rods. Known for its unwavering commitment to quality and precision, the company crafts products specifically designed to meet the rigorous demands of industries like aerospace, power generation, and high-temperature industrial applications. With state-of-the-art manufacturing facilities and strict quality control measures, Mourad Metals guarantees that every Nimonic bar and rod delivers outstanding consistency, reliability, and durability. Their focus on innovation and customer satisfaction makes them a trusted partner for sectors that need top-notch nickel-based superalloys capable of performing under extreme conditions.
Nimonic bars and rods are primarily made from nickel, enhanced with chromium, cobalt, titanium, and aluminum, which together create a perfect blend of high strength, corrosion resistance, and oxidation resistance. These alloys boast impressive mechanical properties, including exceptional creep strength, fatigue resistance, and the ability to maintain their structural integrity at elevated temperatures reaching 700–800°C. The microstructure is engineered to prevent grain boundary weakening, ensuring long-lasting performance even under stress. Additionally, Nimonic materials exhibit stable thermal expansion and hardness, making them perfect for components that face cyclic thermal and mechanical loads in harsh environments.

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.
These Nimonic bars and rods find extensive use in aerospace components like turbine blades, discs, and combustion chambers, where high-temperature performance is essential. They’re also crucial in power generation applications, including gas turbines, nuclear reactors, and industrial furnace components, thanks to their remarkable creep and oxidation resistance. Other uses include chemical processing equipment, high-temperature fasteners, and automotive parts that endure extreme heat and stress. The combination of durability, thermal stability, and mechanical strength makes Nimonic bars and rods vital in various industries.
