Cast iron. Cast iron is a class of iron – carbon alloys with a carbon content of more than 2% and silicon content around 1–3%. [ 1] Its usefulness derives from its relatively low melting temperature. The alloying elements determine the form in which its carbon appears: white cast iron has its carbon combined into an iron carbide named ...

Malleable iron. Wrought iron. Micrograph of grey cast iron. Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. It is named after the gray color of the fracture it forms, which is due to the presence of graphite. [ 1] It is the most common cast iron and the most widely used cast material based on weight.
Ductile iron. Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spheroidal graphite cast iron[ 1] and SG iron, is a type of graphite -rich cast iron discovered in 1943 by Keith Millis. [ 2] While most varieties of cast iron are weak in tension and brittle, ductile iron has much more impact and fatigue ...
The equivalent carbon content concept is used on ferrous materials, typically steel and cast iron, to determine various properties of the alloy when more than just carbon is used as an alloyant, which is typical. The idea is to convert the percentage of alloying elements other than carbon to the equivalent carbon percentage, because the iron ...
Cast iron is a brittle form of iron which is weaker in tension than in compression. It has a relatively low melting point, good fluidity, castability, excellent machinability and wear resistance. Though almost entirely replaced by steel in building structures, cast irons have become an engineering material with a wide range of applications ...
Grey cast iron consists mainly of the microstructure called pearlite, mixed with graphite and sometimes ferrite. Grey cast iron is usually used as cast, with its properties being determined by its composition. White cast iron is composed mostly of a microstructure called ledeburite mixed with pearlite. Ledeburite is very hard, making cast iron ...
Wrought iron. Wrought iron is an iron alloy with a very low carbon content (less than 0.05%) in contrast to that of cast iron (2.1% to 4.5%). 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.
