"Demand for Superalloys in Civil and Military Aviation"Table 1 shows an overview of important alloying metals for superalloys
Table 2 Military aircraft superalloy demand in the next 20 years. A total of 24,000 new engines are estimated to be required
Table 3 Civil aircraft demand and superalloy demand in the next 20 years This number depends on the weight of the engine, the number of engines per aircraft, and the life of the superalloy components within the engine. Assuming that each new commercial aircraft is a twin-engine aircraft, the average weight of each engine is about 3 tons. With it came turbines for land-based power generation and superalloys for different types of rockets. Quantities are in tonnes of metal.
Table 4 Summary of superalloy demand in the next 20 years, tons of metal The flow of superalloy compositions is shown in Figure 1. We also indicate whether these metals are soft-scarce (compensated by higher prices) or hard-scarce (compensated by higher prices and are actually limited in quantity that can be delivered). Figure 1 A diagram explaining the flow of metal to each jet engine
