Editor’s Note: Driven by the demand for lightweight materials in the automotive industry, the transport segment remains the largest market segment in the global aluminum market. In 2024, this segment accounted for a market share of some 28% (Figure 1)—a figure that is expected to increase annually over the next decade.1
Not surprisingly, China’s transportation sector accounts for the largest share, followed by Europe and then North America. In the U.S., transportation accounted for 35% of the aluminum and aluminum products market in 2024.2
The largest sub-segment in the transportation sector remains automotive. Lots of aluminum is being used in passenger vehicles in structural components, powertrains, and other applications, in the form of castings, extrusion, and sheet. The reason for this is clear: Lightweighting improves fuel efficiency and lessens greenhouse gas emissions, which are still among the drivers for internal combustion engine vehicles.
Around 20% of greenhouse gas emissions are generated by the transportation sector, according to research from the International Energy Agency.3 Therefore, putting transportation vehicles on a diet is necessary toward cutting greenhouse gas emissions.
Of course, transportation as the aluminum industry’s largest market segment includes more than automotive. Aluminum is a popular choice for car bodies in high-speed trains, as well as in the bodies and other structural applications used for street and transit buses. In addition, shipbuilders build massive vessels with their hulls, cabins, and structural parts in aluminum, and fishing boats and pleasure crafts also use a lot of aluminum.
The inherent properties of this metal are just so incredibly useful across the transportation sector. Add to that the growing appetite for secondary metal and an improving reputation as a sustainable material, and it is easy to see how aluminum will remain a hot item in the transportation segment.
The patents presented below each have a link to the transport segment, and each was granted during the course of the past year. They are also available online at: https://patents.google.com, www.uspto.gov/patents/search, and https://patents.justia.com/patents-by-us-classification.

US12397918B1 — FUEL CELL TURBOELECTRIC FAN FOR AN AIRCRAFT — Tennessee Technological University (USA) — In recent times, there has been a growing interest in hybrid-electric propulsion systems for aircraft. However, the switching stations or terminal stations necessary in these current systems tend to be relatively heavy, resulting in inefficiencies in the design of hybrid-electric aircraft. Therefore, the development of a propulsion system for an aircraft capable of addressing these limitations would be highly advantageous. A challenge is the massive amount of electricity that has to be distributed throughout the aircraft. The large amount of electrical power that typically has to be distributed requires significant mass and volume for transmitting the electrical power (copper/aluminum wires) or superconducting electrical distribution system. The aircraft propulsion system disclosed herein is a transformative technology dramatically increasing efficiency and capability while being fuel-flexible for both small and large aircraft platforms.
US12258132B1 — AIRCRAFT SEAT FRAME — Abdelilah Chennaoui and Aamir Jafri (USA) — Conventional aircraft seat frames incur a high cost to manufacture. Additionally, because of the number of parts used to make conventional aircraft seats, manufacturing is complex due to the design and the design is difficult to certify.

These requirements include excellent fatigue damage resistance, corrosion resistance, and heat resistance. In this context, aluminum alloys remain essential in the aerospace field due to their light weight, high strength and good processability. In particular, al-Cu-Mg series aluminum alloys, which are part of the 2xxx series, not only have high specific strength, but also exhibit good heat resistance and high fatigue damage resistance. This invention mainly aims to provide a high-strength damage-resistant 2xxx aluminum alloy, a preparation method and application thereof, and aims to solve the problem that aviation aluminum alloy in the prior art is difficult to have high specific strength and high damage tolerance performance.
