Aiman Metals, Kuala Lumpur, Malaysia, is a prominent manufacturer and supplier of high-performance Nimonic Bars and Rods to industries requiring superior performance under severe conditions. With a high reputation for precision engineering and dependability, the company supplies products customized to industries like aerospace, power generation, and automotive. Recognized for their exceptional strength, toughness, and capability to maintain extremely high temperatures, Aiman Metals’ Nimonic products adhere to international quality standards. Produced in various sizes and specifications, these rods and bars offer reliable performance, making Aiman Metals a reliable partner for critical engineering and high-technology applications.
Nimonic Rods and Bars are nickel-based, high-performance alloys with about 50–70% nickel, 14–22% chromium, 2–20% cobalt, 2.8–3.5% titanium, and 1.5–2.5% aluminum. Trace elements including carbon, iron, and molybdenum are incorporated to improve strength and resistance to oxidation. The alloys have tensile strengths of up to 1,300 MPa, good creep resistance at temperatures near 1,000°C, and better corrosion resistance in hostile environments. Engineered for mechanical stability under severe stress and temperature, Nimonic is able to maintain structural integrity and can be used in critical aerospace components, high-speed gas turbines, and other severe industrial uses.

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 Rods and Bars have wide application in industries where strength, durability, and heat resistance are critical. In the aerospace industry, they are used for exhaust systems, turbine blades, and parts of an engine subjected to high temperatures. In the power generation industry, they are utilized in steam plant components, heat exchangers, and components of gas turbines owing to their oxidation and creep resistance. In the automotive industry, they are used in high-performance exhaust valves and turbocharger components. Their resistance to both thermal and mechanical stress maintains their mechanical integrity, so Nimonic is well-suited for sophisticated engineering applications where reliability and long life are paramount.
