Maduka Metals is a trusted manufacturer and supplier of premium Alloy C263 Bars and Rods based in Abuja, Nigeria. Renowned for delivering superior quality and precision-engineered materials, we specialize in high-performance nickel-based alloys designed to withstand extreme conditions. Our Alloy C263 Bars and Rods are produced using advanced metallurgical techniques to ensure outstanding mechanical strength, corrosion resistance, and thermal stability. Serving industries such as aerospace, petrochemical, power generation, and engineering, Maduka Metals is dedicated to providing reliable, high-strength materials that meet international standards and support Nigeria’s growing industrial and manufacturing needs.
Alloy C263 is a superalloy made from nickel, chromium, and cobalt, enhanced with iron, manganese, silicon, and trace elements to boost its strength and resistance to corrosion. Typically, it contains around 18–21% chromium, 16–20% cobalt, and 2–4% molybdenum, which contribute to its outstanding high-temperature performance. In terms of mechanics, Alloy C263 bars and rods showcase impressive tensile and yield strength, excellent creep resistance, and remarkable fatigue properties. This alloy maintains its structural integrity even under extreme thermal conditions and resists oxidation and scaling, making it perfect for high-stress environments where durability and consistent mechanical performance are essential.

Yes, Alloy C263 bars are recyclable. As a high-performance alloy, it can be melted and reused for manufacturing new products, making it an environmentally friendly material in the long term.
Alloy C263 rods are available in various sizes ranging from 1/8" to 6" in diameter, with lengths typically up to 12 feet. Common finishes include hot-rolled, cold-drawn, and polished.
Yes, Alloy C263 (also known as Hastelloy C263) can be welded using appropriate techniques such as TIG or MIG welding, with careful control of heat to avoid carbide precipitation.
Alloy C263 Bars and Rods are extensively used in high-temperature and high-stress environments. They are ideal for gas turbine components, combustion chambers, seals, rings, and fasteners in the aerospace and power generation industries. In petrochemical plants, they are employed in reactor vessels, heat exchangers, and pressure systems due to their resistance to oxidation and creep. The alloy’s excellent fabricability allows for easy machining and forming, supporting complex design requirements. Its stability and strength retention at elevated temperatures make Alloy C263 a preferred material for critical applications requiring long-term reliability and performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
