How FC and FCD Cast Iron Differ

FC (Ferritic Cast Iron) and FCD (Ferroductile Cast Iron) are types of cast iron with different properties and applications as follows:

FC (Ferritic Cast Iron)
     Composition: This is a cast iron with a ferritic structure, consisting of high amounts of iron and carbon
     Properties:
         High strength and good wear resistance
         Resistant to rust formation
         High toughness
     Applications: Suitable for parts that need to withstand impact, such as engine components or machinery parts.

FCD (Ferroductile Cast Iron)
     Composition: This type of cast iron is alloyed with materials that enhance its toughness, such as nickel or manganese, making the iron ductile with high flexibility.
     Properties:
         High toughness and flexibility
         Resistant to wear and temperature changes
         Durable against impact and cracking
     Applications: Used in parts requiring high durability and the ability to absorb impact, such as engine cylinder heads or parts used in heavy industries.

Both types of cast iron are strong and durable, but FCD is more suitable for applications that require greater toughness and flexibility than FC.
