INCONEL® alloy 718SPF TM is a specifically "tailored" version of INCONEL alloy 718, designed for the superplastic forming process. The alloy is optimized for the process by rigorous control of composition, melt practice and rolling conditions.

INCONEL alloy 718SPF was developed to meet the need for a nickel-base alloy suitable for manufacture into complex shaped components subject to a combination of high temperature, high temperature corrosion and high stress. INCONEL alloy 718SPF meets all the mechanical property requirements of AMS 5596G, as annealed plus aged, as well as all requirements of AMS 5950, which is specific to INCONEL alloy 718SPF.

Superplastic forming, now highly sophisticated and used extensively for producing commercial and military aircraft components, is an ideal process for manufacturing complex shaped parts. Use of superplastic forming can enhance component performance and reliability while lowering overall manufacturing cost by reducing the need for extensive welding or other joining methods, lowering the inventory of parts and simplifying the manufacturing process.
