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
