Comparison: Cast Iron vs. Ductile Iron
| Property | Cast Iron | Ductile Iron |
|---|---|---|
| Impact Resistance | Poor, breaks under severe impact | Strong, bends under impact |
| Tensile Strength | Low, 350 N/mm² | High, 500 N/mm² |
| Elongation/Ductility | None | Moderate, 7% minimum |
| Weight | Heavier for specific duty | Lighter (2/3rd weight of cast iron) |
| Handling | Difficult due to weight | Easier due to lighter weight |
| Vibration Absorption | Poor | High |
Material Grade and Application Areas:
| Class – Material Grade | Area of Application |
|---|---|
| A 10 | Areas for pedestrians and cyclists only |
| B 125 | Car parks, footways, and areas accessible to light vehicle traffic |
| C 250 | Kerbside channels extending up to 500mm into the carriageway |
| D 400 | Roads carrying heavy traffic, pedestrian areas, and roads accessible to all types of vehicles |
| E 600 | High-traffic areas such as docks and aircraft pavements |
