Alloys are mixtures of metal—such as iron, coal, copper, tin, and lead—with other metals or with nonmetallic elements developed to add desirable properties to those possessed by the metallic elements. These properties include strength, hardness, resistance to corrosion, and the ability to withstand high temperatures. The properties of alloys depend not only on their chemical composition but also on the way they have been prepared. Steel, a family of alloys based on the addition of carbon... więcej
