Wrought iron is an iron alloy with a very low carbon content (less than 0.08%) in contrast to that of cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure.Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welded ...

Maraging steels (a portmanteau of "martensitic" and "aging") are steels that are known for possessing superior strength and toughness without losing ductility. Aging refers to the extended heat-treatment process. These steels are a special class of very-low-carbon ultra-high-strength steels that derive their strength not from carbon, but from precipitation of intermetallic …
Codelco (Corporación Nacional del Cobre de Chile or, in English, the National Copper Corporation of Chile) is a Chilean state-owned copper mining company. It was formed in 1976 from foreign-owned copper companies that were nationalised in 1971.. The headquarters are in Santiago and the seven-man board of directors is appointed by the President of the Republic.
