There are four basic types of cast iron - white iron, gray iron, ductile iron and malleable iron

There are four basic types of cast iron

white iron
gray iron
ductile iron
malleable iron

White Cast Iron

Characterized by the prevalence of carbides, impacting

high compressive strength
hardness
good resistance to wear

Gray Cast Iron

Characterized with graphite in the microstructure, giving

good machinability
good resistance to wear and galling

Ductile Cast Iron

Gray iron with small amounts of magnesium and cesium which nodulates the graphite, resulting

high strength
high ductility

Malleable Cast Iron

White cast iron heat-treated to improve

higher ductility
