ZYTC Alloy is an ISO 9001 and AS 9120B certified superalloy manufacturer and supplier, offering AMS 5544L Waspaloy annealed sheet at factory-direct prices with full material traceability and fast global delivery. AMS 5544L specification covers a corrosion- and heat-resistant nickel alloy (Waspaloy / UNS N07001) in the form of sheet, strip, and plate. Waspaloy is a nickel-based age-hardenable alloy that possesses high-temperature strength while maintaining good corrosion resistance, especially to oxidation. It can be used at temperatures up to 650°C (1200°F) for critical rotating applications. The alloy is widely used in gas turbine engine components, missile systems, shafts, spacers, seals, rings, casings, fasteners, and many other engine hardware and airframe assemblies.
Specifications & Available Waspaloy is a precipitation-hardenable nickel-base superalloy strengthened by the formation of gamma-prime [Ni₃(Al,Ti)] during aging. The alloy is produced using consumable electrode or vacuum induction melting (VIM) to ensure high purity and metallurgical consistency. The AMS 5544L condition is annealed, providing a soft, workable state for forming and fabrication prior to final heat treatment. The anneal is performed at 1975°F (1080°C) for 30 minutes followed by air cooling. Available Forms: Sheet, strip, plate; also round bar, flat bar, forging stock, extruded section, wire, and welding wire Specifications: AMS 5544L (sheet/strip/plate), AMS 5704 (bar/forgings), AMS 5708 (bar/forgings/VAR), AMS 5828 (wire), ASTM B637, UNS N07001
Fabrication & Material ComparisonAnnealing (As-Supplied): 1080°C (1975°F) × 30 mins, air cool Solution Treatment: 996°C (1825°F) × 2 hours, air cool Stabilization: 843°C (1550°F) × 4 hours, air cool Aging: 760°C (1400°F) × 16 hours, air cool Forming: Excellent ductility in annealed condition; suitable for deep drawing, stamping, and bending Machining: Good machinability in annealed condition; more difficult after aging Welding: Good weldability using GTAW (TIG); matching filler metal (AMS 5828) recommended; post-weld heat treatment required to restore properties
