Grey Iron Properties, Uses and Close Competitor

Grey iron castings are mainly used in instances where there is no worrying about an item breaking because there is no pressure being applied on it. They have graphite in them, which gives the gray color, and the graphite is formed during the slow cooling process.

They are the most common type of castings used because they can be used for different applications. They also have high heat conductivity so cast iron can be used to make disc brake rotors and cookware. They are also used in the making of pump housings, decorative castings and internal engine cylinder blocks.

A grey iron casting company that is good at what they do knows that different amounts of graphite, formed during cooling, determine the quality of the iron castings.  Good quality castings are an assurance of good quality end products.

Compacted graphite iron (CGI) is fast gaining popularity. It also has some graphite in it like cast iron but its particles are thicker and shorter than those in cast iron. This makes the bond between the iron and graphite stronger. This allows CGI to withstand more pressure since it doesn’t break easy compared to cast iron.
