Cast Iron is Fe (Iron) with a proportion of: C Carbon (2.5 to 4.5%) makes the iron easier to cast and machine. Si
Cast Iron Types | Metal Casting Resources
The primary difference in production between wrought iron and cast iron is that cast iron is not worked with hammers and tools. There are also differences in composition—cast iron contains 2–4% carbon and other alloys, and 1–3% of silicon, which improves the casting performance of the molten metal.
Chemistry for Kids: Elements - Iron
Iron becomes significantly harder when alloyed with other elements such as carbon. Iron can be found in four allotropic forms. The most stable form of iron at normal temperatures is alpha iron which is commonly known as ferrite. Where is iron found on Earth? Iron is the most abundant element in the Earth. The Earth's core is mostly made up of an iron-nickel alloy. Iron also makes up about 5% of the Earth's crust where it is the fourth most abundant element.
Iron (Fe) - Atomic Mass & Number, Melting Point, Chemical and ...
Iron is a chemical element in the periodic table that has the symbol Fe and atomic number 26. Iron is a group 6 and period 4 metal. Iron is notable for being the final element produced by stellar nucleosynthesis, and thus the heaviest element which does not require a supernova or similarly cataclysmic event for its formation.
Iron | Minerals Education Coalition
Iron is the third most common element making up the Earth. Iron is one of the three naturally magnetic elements; the others are cobalt and nickel. Iron is the most magnetic of the three. The principle ores of iron are hematite (70% iron) and magnetite (72% iron). Taconite is a low-grade iron ore, containing up to 30% magnetite and hematite.

The Advantages of Iron | HowStuffWorks
The element has been useful to people for thousands of years, while aluminum really didn't exist in any meaningful way until the 20th century. Advertisement Fortunately, iron can be created relatively easily with tools that were available to primitive societies.
Iron - Wikipedia
An increase in the carbon content will cause a significant increase in the hardness and tensile strength of iron. Maximum hardness of 65 R c is achieved with a 0.6% carbon content, although the alloy has low tensile strength. Because of the softness of iron, it is much easier to work with than its heavier congeners ruthenium and osmium.
Iron | Fe (Element) - PubChem
Iron is hard, brittle, fairly fusible, and is used to produce other alloys, including steel. Wrought iron contains only a few tenths of a percent of carbon, is tough, malleable, less fusible, and usually has a "fibrous" structure. Carbon steel is an alloy of iron with small amounts of Mn, S, P, and Si.
