Nestled in the heart of Kinshasa, Congo, Sadiki Metals stands as a trusted partner for industries demanding exceptional performance from their materials. We specialize in the manufacturing and supply of Nimonic 90 bars and rods, providing local and regional businesses with direct access to this premier high-temperature alloy. Our commitment is to deliver not just metal, but reliable engineering solutions that empower your most challenging projects, backed by a deep understanding of the unique demands faced by sectors across Africa and beyond.
The strength of Nimonic 90 lies in its sophisticated composition, primarily nickel and chromium, with significant additions of cobalt and titanium. This careful balance gives the alloy its remarkable mechanical properties, including impressive tensile strength and outstanding resistance to creep. It retains these strengths even when subjected to the intense heat and stressful conditions that would cause ordinary steels to fail, making it a consistently reliable material in high-stakes environments.

Yes, Nimonic 90 bars are highly suitable for high-temperature applications. They are known for excellent strength, oxidation resistance, and stability at elevated temperatures, making them ideal for aerospace and turbine components.
Yes, Nimonic 90 bar can be welded, but it requires careful control of heat and welding parameters. Typically, TIG (Tungsten Inert Gas) welding is recommended for best results.
Nimonic 90 rod is available in various sizes, typically from 1/8" to 12" in diameter. Common finishes include cold drawn, hot rolled, or bright polished, depending on the supplier.
Because of its ability to withstand extreme heat and stress, Nimonic 90 is indispensable in critical applications. You will find it at the core of gas turbine engines, forming essential components like turbine blades and discs. Beyond aerospace, it is vital in the hot working tools for extrusion and forging dies, and it plays a key role in high-performance automotive engines and exhaust systems. Essentially, wherever temperatures soar and reliability is non-negotiable, Nimonic 90 provides the necessary durability.
