Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The sharp hike in U.S. tariffs and the associated trade disputes in spring 2025 are notably impacting the aerospace and defense sector by raising costs for titanium, carbon fiber composites, and avionics materials largely sourced from global suppliers. Defense contractors, locked into fixed-price government contracts, absorb these added costs, while commercial aerospace firms face airline pushback on higher aircraft prices. Delays in component shipments due to customs bottlenecks further disrupt tight production schedules for jets and satellites. The industry is responding by stockpiling critical materials, seeking waivers for defense-related imports, and collaborating with allied nations to diversify supply chain.

Shape memory alloy (SMA) actuators are devices crafted from specialized metals that deliver controlled movement or force in response to variations in temperature or electrical current. These actuators convert thermal energy into mechanical motion, offering precise and space-saving actuation capabilities. Shape memory alloy (SMA) actuators enable efficient, silent, and compact motion, making them suitable for use in applications like robotics and medical devices.

Shape memory alloy (SMA) actuators primarily consist of linear motion actuators, micro-actuators, and valve actuators. A linear motion actuator functions by transforming energy into straight-line motion to accurately move or position objects. These actuators utilize different activation mechanisms such as electrical, magnetic, pressure, and thermal triggers. Technologies embedded in these actuators include bio-integration, IoT integration, nanotechnology, and smart materials. The actuators are developed using various material types, including copper-based alloys, iron-based alloys, and nickel-titanium (Nitinol), and serve end-user industries such as aerospace and defense, automotive and transportation, construction and infrastructure, consumer electronics and appliances, and the medical and healthcare sector.
