A Brief Look at How Cast Iron Is Formed
Grey cast iron is a form of cast iron with a complex graphitic structure. It's named after the greenish grey colour of the grey cast that it forms, which is probably due to the presence of manganese. It's the second most popular cast iron used for domestic use, behind only steel, and is also the second most widely utilised grade of alloy in the world (after aluminium).
Like all metals, the fundamental properties of grey cast iron (which includes high compressive strength, good thermal conductivity, good compressive strength and excellent ductility) are determined by the chemical composition of the alloy. By comparing the electrical and physical properties of pure aluminium and pure nickel, it's possible to identify the alloy composition that gives each material its specific strength. Cast...
