Cast Iron
------------------------------------------------------------------------------
3. Low Melting Point:
The melting temperature of cast iron ranges from 1140 ºC to 1200 ºC. Nowadays, many advanced melting, alloying and casting methods are being used, which can bring the new irons formed, in competition with steel.
4. Resistance to Deformation:
Cast iron structures show resistance to deformation and provide a rigid frame. However, if one part of the casting after the iron is poured into the molds, is very thin, and another very thick, the problem of the structure breakdown becomes prominent. The reason for this is when the thin part cools first and contracts, the thick part which cools down afterward causes stress in the thin part, offering sufficient force to break it.
5. Resistance to Oxidation:
Rust is formed by the reaction of iron and oxygen, in the presence of water or air moisture. It leads to the corrosion of iron and its alloys, and any iron mass in presence of water and oxygen, can eventually convert into rust and later disintegrate. As cast iron offers resistance to oxidations, it provides a solution to the problem of rust.
