Waspalloy

Waspaloy (UNS N07001) is a nickel-based, precipitation-hardening superalloy built for high strength at elevated temperatures. Its strength comes from solid solution elements like chromium (18–21%), cobalt (12–15%) and molybdenum (3.5–5.0%), along with aluminum (1.0–1.5%) and titanium (2.6–3.25%) that provide age hardening. Small amounts of carbon, zirconium, and boron improve toughness and grain control, while nickel acts as the base. With a minimum elongation of 25%, this balance allows Waspaloy to give a tensile strength of up to 150 ksi and a yield strength of 85 ksi. For rotating parts, the alloy works reliably at service temperatures of 1200°F (650°C), and for less demanding applications, it can reach up to 1600°F (870°C). Parag Metals supplies Waspaloy in multiple forms for industries that need reliable performance in severe operating conditions.

With a density of 8.20 g/cm³ it has a stable structure under stress. Its melting range lies between 1330–1360°C (2425–2475°F), giving it excellent thermal endurance. The alloy shows low thermal conductivity. It is also non-magnetic, which makes it useful in specialized aerospace and defense systems. These physical traits, combined with its chemical makeup, make Waspaloy a reliable choice when both strength and resistance are critical.

Fabrication of Waspaloy requires careful handling. Hot working is best performed between 1850–2150°F with finishing above 1850°F to avoid surface damage. Cold working is possible but the alloy hardens rapidly, requiring frequent annealing. Machinability is challenging; it needs rigid equipment, sharp carbide tools, and controlled cutting speeds. Best results come when machining in the solution-treated condition. Welding is possible if the alloy is in annealed or solution-treated form, but it requires clean surfaces, argon shielding, and rapid cooling to reduce strain-age cracking. Each fabrication step must be planned carefully to maintain the alloy’s strength and stability.

To meet different industrial needs, Waspaloy is supplied in wire, extruded sections, round bars, and forging stock. It is manufactured according to ASTM B637 for bars and rods, AMS 5544 for plates and sheets, and AMS 5708 for forging stock. In gas turbine engines, where high strength and resistance to corrosion are important, the alloy is widely used. Some applications include compressor and rotor discs, shafts, rings, casings, spacers, fasteners, seals, and other engine hardware. Alongside turbines, it is used in missile systems and airframe assemblies where a long service life under stress is important. Being a reputable Waspaloy supplier, we ensure a steady supply and guaranteed alloy performance.
