From the bustling industrial heart of Addis Ababa, Tariku Metals proudly serves as your trusted local manufacturer and supplier, specializing in high-performance materials for demanding applications. We are particularly dedicated to providing top-quality Nimonic 80A bars and rods, ensuring that Ethiopian industries have direct access to this exceptional superalloy. Our commitment lies in delivering not just a product, but a reliable partnership built on technical expertise and a deep understanding of the local market’s needs, empowering progress with materials built to last.
Nimonic 80A stands out due to its specialized composition, primarily a nickel-chromium alloy strengthened with additions of titanium and aluminum. This unique recipe gives it a remarkable combination of high tensile and creep strength, allowing it to perform reliably under substantial loads and extreme temperatures. It also maintains excellent corrosion resistance and good抗氧化 properties, making it a robust material choice. These consistent mechanical properties ensure it can handle the severe stresses encountered in critical engineering environments.

Yes, Nimonic 80A, a nickel-based alloy, can be susceptible to galvanic corrosion when in contact with materials that have significantly different electrochemical potentials, especially in the presence of an electrolyte.
Yes, Nimonic 80A bar can be welded. It is commonly welded using techniques like TIG or MIG welding, with preheating and post-weld heat treatment to prevent cracking.
Nimonic 80A bars are available in various sizes, typically from 6mm to 250mm in diameter, and lengths up to 6 meters. Common finishes include bright, polished, and cold-drawn.
The exceptional strength and resistance of Nimonic 80A bars and rods make them indispensable in sectors where failure is not an option. They are widely used in aerospace for turbine blades and engine components, and in industrial gas turbines for crucial parts requiring long-term durability. You will also find them in high-performance automotive valves, nuclear engineering systems, and industrial fasteners for high-temperature assemblies. Essentially, wherever intense heat and stress are a constant challenge, Nimonic 80A provides the reliable solution needed for safety and efficiency.
