Cast Iron
Cast iron tends to be brittle, except for malleable cast irons. With its low melting point, good fluidity, castability, excellent machinability and wear resistance, cast irons have become an engineering material with a wide range of applications, including pipes, machine and car parts.
Iron (Fe) accounts for more than 95 %wt of the alloy material, while the main alloying elements are carbon (2.1 to 4 %wt) and silicon (1 to 3 %wt).
Material properties:
| Density kg/m3 | 7000 to 7400 |
| Modulus of elasticity E GPa | 83 to 170 |
| Modulus of elasticity G GPa | 32 to 69 |
| Poisson's ratio v | 0.2 to 0.3 |

Lathe Tool Angles
Lathe tool angles for turning cast iron:
| Material | Side clearance ° | Front clearance ° | Side rake ° | Back rake ° |
| Cast Iron | 10 | 8 | 12 | 5 |
