Applications of Gold in Aerospace Engineering
Applications of Gold in Aerospace Engineering

Summary/Abstract: Gold plays a critical role in aerospace engineering due to its unique combination of physical and chemical properties. Its exceptional thermal and electrical conductivity, corrosion resistance, infrared reflectivity, and malleability make it indispensable in spacecraft, satellites, and astronaut safety systems. Despite its high cost and density, gold is strategically used in thin coatings and advanced electronic components where performance and reliability are paramount. This paper explores gold's diverse aerospace applications, including thermal control, electronics, propulsion, and life-support systems. It also examines emerging technologies such as nanostructured gold, additive manufacturing, and sustainable use strategies that promise to expand its role in next-generation space missions
