Applications of grey iron castings
Introduction to Grey Iron Castings
It is a type of cast iron which is characterised by a graphitic microstructure
It is named so, due to the presence of graphite which leads to a creation of fracture which is grey in colour
Key characteristics of grey iron castings are high specific heat capacity and thermal conductivity
Advantage of Grey Iron castings
Relatively less costlier compared to other types of iron casting
Since graphite lubricates the cut, it has a good machinability
Excellent resistance to wear and galling due to self-lubrication of graphite flakes
Cost economical
Uses and Applications of Grey Iron Castings
Controlling or damping vibrations in a vast range of applications
Applications that require Dimensional stability High strength to weight ratios
Flexibility in formulation which enables to meet particular requirements of different applications
Applications of Grey Iron Castings Due to the flexibility in its metallurgy, grey iron castings find a vast range of applications. Some of them include:
Forges
Pumps and valves
Rolling mills and foundries
Aerospace and automotives
Vast range of Original Equipment Manufacturing’s (OEMs)
Mines and quarries
Local civil authorities
Rolling stock and railways
Sculptors
Artists
