Corrosion is a natural process, which converts a refined metal to a more chemically-stable form, such as its oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usual metals) by chemical and/or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and stopping corrosion. In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen or sulfur. Rusting, the formation of iron oxides is a well-known example of electrochemical corrosion. Metals and alloys are materials that are typically hard, malleable, and have good electrical and thermal conductivity. Alloys are made by melting two or more elements together, at least one of them a metal. They have properties that improve those of the constituent elements, such greater strength or resistance to corrosion.
The technology of shaping oldest materials is called metal casting. Casting means molten metal is pouring into a mold with an orbit of the shape to be created, and allowing it to solidify.

The metal casting industry plays a key role in all the major sectors of economy. There are castings sectors like in locomotives, cars trucks, aircraft, office buildings, factories, schools, and homes.
