Grey Cast Iron Casting in Pakistan
Lahore Casting pours Grey Cast Iron (FG200, FG260, FG300) to order at Mominpura Road, Lahore, Pakistan, by sand casting from 1 kg to 500 kg. The oldest and most forgiving casting iron. Flake graphite makes it damp vibration, machine easily and fill thin sections - which is why machine bases and housings have been made from it for two centuries. Every heat is checked on an OES spectrometer before pouring and a material test certificate is issued on request.
Grades and properties
| Grades poured | FG200, FG260, FG300 |
|---|---|
| Grade meaning | FG260 means 260 MPa minimum tensile strength |
| Tensile strength | 200-300 MPa |
| Compressive strength | roughly 3-4x its tensile - it belongs in compression |
| Damping | The best of any casting alloy here |
When to choose it
Use Grey Cast Iron when: Housings, machine bases, pulleys, flywheels, counterweights, brake drums - compression, vibration, or a lot of machining.
Choose something else when: The part sees impact or tension. Grey iron gives no warning before it breaks; use SG iron.
