What is C.I. casting, and why is cast iron still everywhere?

C.I. stands for cast iron. In C.I. casting, iron is melted, poured into a mould shaped like the part, and left to solidify. Once cooled, the casting is removed from the mould and cleaned.

Why manufacturers choose cast iron

• Castability: molten cast iron flows well, so it fills complex shapes such as motor bodies and valve parts.
• Vibration damping: cast iron absorbs vibration, which helps in housings for rotating equipment.
• Machinability: it machines cleanly, so castings can be finished to fit.
• Compressive strength and wear resistance for parts that carry load.
