Alloy
In space and astronautical engineering, an alloy is a metallic substance composed of two or more elements, at least one of which is a metal. Alloys are used extensively in the construction of spacecraft and their components due to their desirable properties such as high strength, low weight, and resistance to corrosion and fatigue. The selection of alloys for specific applications is based on a variety of factors including the operating environment, the required mechanical properties, and the manufacturing process. Common alloys used in space and astronautical engineering include aluminum alloys, titanium alloys, and nickel-based superalloys.
