Chuck Metals, a top-notch manufacturer and supplier based in Singapore, Pulau Ujong, specializes in high-quality Alloy C263 Bars and Rods, crafted for applications that demand high strength and can withstand extreme temperatures. Alloy C263 is a nickel-based superalloy celebrated for its remarkable creep resistance, oxidation resistance, and thermal stability, even at temperatures soaring up to 1000°C. Tailored for critical sectors like aerospace, power generation, and industrial environments, Chuck Metals provides Alloy C263 bars and rods in both solution-annealed and age-hardened forms. Renowned for their consistent quality, precise dimensional tolerances, and adherence to AMS 5886 and related standards, these products guarantee long-lasting performance in the toughest mechanical and thermal conditions.
Alloy C263 is a precipitation-hardenable nickel alloy that consists of Ni (balance), Cr (~20%), Co (~20%), Mo (~5.8%), Ti (~2.1%), Al (~0.6%), along with trace elements like Fe, Mn, and Si. After undergoing aging, the alloy achieves a tensile strength of up to 1080 MPa, a yield strength of around 760 MPa, and a hardness rating between 30–36 HRC. It retains its strength and structural integrity even at elevated temperatures, while also providing good formability, weldability, and oxidation resistance—making it a go-to choice for components that face extreme mechanical and thermal stresses.

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, also referred to as UNS N08028, is a nickel-chromium-iron alloy that has great resistance to oxidation, corrosion, and high temperature. It finds applications in aerospace, chemical processing, and power generation industries. The alloy has a special value in applications involving resistance to sulfuric acid, hydrochloric acid, and phosphoric acid, which qualifies it for the use in heat exchangers, reactors, and furnace components. Alloy C263 bar and rod is also applied on components of the turbine engine, petrochemical equipment, and marine applications. Due to its elevated temperature strength and resistance to aggressive environments, this alloy is highly suitable for demanding applications in both industrial and high-performance environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
