Metallic Substance
In space and astronautical engineering, a metallic substance refers to any material that is composed of metal atoms or alloys. Metallic substances are commonly used in the construction of spacecraft and their components due to their high strength, durability, and resistance to extreme temperatures and radiation. These materials are also used in the production of rocket engines, fuel tanks, and other critical components that require high strength-to-weight ratios. Metallic substances can be further classified into ferrous and non-ferrous metals, with ferrous metals being those that contain iron and non-ferrous metals being those that do not contain iron. Examples of metallic substances commonly used in space and astronautical engineering include aluminum, titanium, steel, and copper alloys.
