Nimonic 80A is a wrought, age-hardenable nickel-chromium alloy, strengthened by additions of titanium, aluminum and carbon, developed for service at temperatures up to 815°C (1500°F). It is produced by high-frequency melting and casting in air for forms to be extruded. The alloy also withstands attack from acidic and alkaline environments, making it suitable for chemical processing.

Alloy 80A tube can be both hot and cold formed. However, Nimonic alloy 80A, also known as N07080, is typically more ductile and easier to form at elevated temperatures, hot forming processes include techniques such as hot forging, hot rolling, and hot extrusion. The material is heated to a temperature within the range of approximately 950 to 1150°C (1742 to 2102°F) to enhance its plasticity and enable shaping into the desired form. Proper control of the heating temperature and cooling rate after forming is essential to maintain the desired properties of the material.

• Oxidation Resistance: Nimonic 80A, also known as alloy 2.4952, alloy 2.4631, exhibits excellent oxidation resistance primarily due to chromium in the alloy forms a stable chromium oxide (Cr2O3) layer on the surface, this oxide layer acts as a protective shield, preventing the underlying material from direct contact with oxygen and corrosive gases,  acting as a barrier against further oxidation. Moreover, the presence of aluminum helps in the formation of a dense and adherent alumina (Al2O3) layer on the surface, this alumina layer acts as an additional barrier, effectively inhibiting the diffusion of oxygen and protecting the alloy from rapid degradation at high temperatures, further enhancing the oxidation resistance of alloy 80A.

• High Strength: The alloy exhibits outstanding high strength primarily due to its unique composition and microstructure. Nimonic 80A tube is strengthened through the addition of elements such as nickel, chromium, and titanium, which form a solid solution matrix. This solid solution structure enhances the material's resistance to deformation and improves its mechanical properties. Additionally, the presence of fine precipitates of secondary phases, such as gamma prime (γ') and carbides, further contribute to strengthening the alloy.

• Good Weldability: Alloy 80A tube is readily joined by any of the resistance welding processes. For section thicknesses up to about 5 mm, fusion welding by conventional processes such as T.I.G. or M.I.G. is satisfactory. For section thicknesses greater than 5 mm, electron beam, friction, inertia and flash-butt welding have all been successfully used. Post-weld heat treatment is necessary to achieve optimum properties.

Nimonic alloy 80A, also referred to as GH3039, stands as a high-performance nickel-based alloy renowned for its exceptional attributes that cater to demanding industrial needs. This alloy, when subjected to diverse surface finishing treatments like Acid Pickling (AP), Mechanical Polishing (MP), Bright Annealed (BA), and Electropolishing (EP), not only enhances its visual appeal but also accentuates its unique properties.

Nimonic 80A tube are integral components across industries including aerospace, energy, chemical processing, oil & gas, and more, owing to their exceptional high-temperature strength, oxidation resistance, and corrosion resistance. These tubes are utilized in aircraft engines, gas turbines, and various critical applications where reliability and performance in extreme conditions are imperative, highlighting their versatility and importance in diverse industrial settings.
