ZYTC Alloy, a trusted Chinese manufacturer and supplier of high‑end aerospace nickel‑base superalloys, provides premium AMS 5950 & AMS 5914 Alloy 718SPF (UNS N07719) sheets and strips. Alloy 718SPF is a specially optimized superplastic‑forming variant of conventional Alloy 718, engineered for producing intricate, near‑net‑shape aerospace components operating under combined high‑temperature, high‑stress and corrosive service conditions.

Material Overview

AMS 5950 specification governs corrosion‑ and heat‑resistant nickel‑alloy sheet and strip with nominal thickness up to 0.080 inch (2.03 mm), while AMS 5914 covers the expanded specification range for Alloy 718SPF sheet, strip and foil. Designated UNS N07719, Inconel® 718SPF retains the outstanding corrosion‑resistance performance typical of nickel‑chromium superalloys. It fully satisfies mechanical property requirements of AMS 5596G for annealed‑plus‑aged condition, in addition to all dedicated requirements defined within AMS 5950.

Unlike standard Alloy 718, 718SPF is precisely tailored for superplastic forming (SPF) technology. Strict controls over chemical composition, melting route and cold‑rolling schedules deliver uniform fine‑grain microstructure, enabling exceptional superplastic deformation capacity at elevated temperature. This material solves long‑standing manufacturing bottlenecks for complex thin‑wall aerospace structures.

Core Advantages of Alloy 718SPF

Optimized for Superplastic Forming: Controlled fine‑grain microstructure enables large‑deformation SPF, producing highly complex single‑piece components with minimal joints.
Excellent High‑Temperature Performance: Maintains high strength, creep resistance and oxidation resistance under combined thermal load and mechanical stress.
Outstanding Corrosion Resistance: Reliable resistance against various corrosive media, consistent with standard Inconel 718 performance.
Lower Manufacturing Costs: Reduces welding assemblies, part count and secondary machining operations, improving component integrity and reliability for both military and commercial aircraft programs.
Fully Qualified Aerospace Grade: Complies with AMS 5596G, AMS 5950 and AMS 5914 aerospace specifications for critical airborne hardware.
