Two of the largest aircraft engine manufacturers in the United States, Pratt & Whitney and GE Aircraft Engines, are supporting a five-year, industry-wide research effort to improve the temperature capabilities of nickel-base alloys. The most widely applied super-alloy in the aerospace industry is NO7718, which contains 52% nickel.

Applications include critical rotating structures and pressurized vessels. For example, N07719 comprises 34% of the total weight of GE's CF6 engine, and was selected for 56% of the company's rotating and structural ...
