Gray iron castings manufacturer

What are the properties of gray iron castings that make it saleable?

One of the oldest ferrous metals used in construction is cast iron and the most traditional common form of cast iron is gray cast iron which is made by re-melting the pig iron. It is basically an alloy of carbon and iron but many also contain traces of silicon, sulphur, phosphorus, manganese, etc.

Their ability of being made into complex structures and availability at low cost are the main factors of their popularity. Gray iron castings are the most widely used because of the properties they possess. 

The compressive strength of gray cast iron is high which is why it is used as an application in columns and post in buildings. However, the tensile strength varies according to the variety. It has a rigid frame and has a resistance to deformation. It has a low melting point. Another property it has is its resistance to oxidation which is a plus point as it prevents corrosion.

The carbon content in gray iron is flaky and distributed throughout the metal. Although they can be easily cast, they cannot be forged or worked mechanically either hot or cold.

The manufacture still remains the same as it was before where iron ore, coke and limestone are heated in a blast furnace. In this process, deoxidisation of ore takes place that drives away the impurities and thus produces molten iron. This is then poured into moulds in various shapes and sizes as per your desire, allowed to cool and crystallize.
