UNS N07090 (Alloy 90, W.Nr. 2.4632, Nimonic® 90) is a wrought nickel-chromium-cobalt-based alloy, enhanced with titanium and aluminum for added strength. Designed as an age-hardenable, creep-resistant alloy, it excels in service at temperatures reaching up to 920°C (1688°F). The alloy boasts high tensile strength and exceptional resistance to creep, demonstrating good oxidation and corrosion resistance within the range of 815~870°C. Additionally, it exhibits high fatigue strength, along with favorable formability and weldability, even under the stress of repeated cold and heating cycles.

UNS N07263 (Alloy 263, W.Nr. 2.4650, Nimonic® 263) stands out as a nickel-based superalloy celebrated for its outstanding strength, resistance to high temperatures, and impressive corrosion resistance. Specifically crafted for situations that require both elevated strength and oxidation resistance, Nimonic 263 presents a harmonious combination of mechanical properties and thermal stability. Additionally, this alloy showcases commendable weldability, allowing for the construction and connection of components through diverse welding techniques.
