The 1920s
Aircraft Program Evolution
- The first all-aluminum airplane – the Junkers F13 – is introduced in Europe.
- Charles Lindbergh makes the first non-stop solo flight from New York to just outside Paris.
- The propeller on the Spirit of St. Louis was crafted from a new Alcoa aluminum alloy.
Alcoa Aerospace Technology Evolution
- Austenal Laboratories, which later became Howmet Castings, produces an inexpensive, heat resistant alloy–leading to the development of supercharger blades needed for high altitude flight.
- Alcoa develops Alclad sheet, assuring the future of aluminum in aircraft construction. The high-strength, corrosion resistant alloy is used in the B-17 and B-24.
