Materials with the primary aim of transmitting or supporting a force are classified as structural materials. They can be made of metal, ceramic, polymer, or a combination of these materials. Transportation (plane and automobiles), construction (buildings and roads), bodily protection (helmets and body armour), energy production (turbine blades), and other smaller structures such as those used in microelectronics are all possible applications of structural materials.
The science and technology of metals and alloys is known as metallurgy. Metals technology, science related to metal manufacturing, and metal engineering are all terms that can be used to define metallurgy. Metallurgy is also known as metals technology, which refers to the application of science to the fabrication of metals and the engineering of metal components for use in consumer and manufactured goods.
