The doctor put a plaster cast on his broken leg. Therefore, the basic scope of the metallurgical processing of cast iron is to manipulate the type, amount, and morphology of the eutectic in order to achieve the desired mechanical properties. The rest of the chemical makeup is primarily carbon and silicon, in various percentages. Referring only to the binary Fe-Fe3C or Fe-Gr system, cast iron can be defined as an iron-carbon alloy with more than 2% C. Important notice is that silicon and other alloying elements may considerably change the maximum solubility of carbon in austenite (g). Cast Iron is an exceptionally strong and durable material - many original installations from the Victorian era are still in existence in the UK, particularly around London and the north of England. The presence of carbon in this form, as opposed to graphite, is the result of a lower silicon content compared to grey cast iron.
