What is the chemical composition of general metal materials?

Specifically, if the metal is composed of a single metal element, the main chemical component is metal element, such as copper wire, and the main chemical component is metal element copper; If it is an alloy, it is two or more elements that synthesize this alloy, such as silicon steel in alloy steel, and the main chemical elements are iron and silicon; In addition, it also contains other impurities, such as carbon and sulfur. For example, the main chemical composition of carbon steel is iron, which contains carbon in addition to iron.
