Alloy Cast Iron

These grades are classified as either ductile or alloy cast iron. The ductile grades have spheroidal graphite and have reasonable strengths and ductility. The cast grades have flake graphite which results in a very brittle alloy but can offer good dampening and hardness properties.

Alloy Properties
Representative Alloys Ductile and Gray
Applications Gray Iron is low cost material with good wear, galling, and dampening properties. Ductile Iron is alow cost material with properties simliar to steels
Limitations Both: Non-weldable, Gray is a brittle material
Typical Uses Gray: cylinder liners, bearings  Ductle: piping, automotive components
Machinability Good
Weldability Non-weldable
Corrosion Resistance None
