Gray Iron Castings Advantages
At a high level, gray iron is preferred when seeking a low-cost, solution with strength, heat dissipation, and high density. It has a good fluidity and is easily machined.
Gray iron derives its properties from flake graphite in its microstructure. Its unique attributes include excellent machinability. When the composition of the molten iron and its cooling rate are suitable, the carbon in the iron separates during solidification and forms interconnected graphite flakes. The graphite grows edgewise into the liquid and forms the characteristic flake shape. The properties of gray iron also are influenced by the relative hardness of the metal matrix, which is the iron that surrounds the graphite. Microstructural properties are primarily controlled by the carbon and silicon content of the metal and the cooling rate of the casting.
Tensile and Yield Strength
Gray iron does not have a measurable yield strength, the range for tensile strength is 20,000 psi – 60,000 psi.
The relative ability of a material to absorb vibration is evaluated as its damping capacity. The quelling of vibration by converting the mechanical energy into heat can be important in structures and devices with moving parts. Components made of materials with a high damping capacity, like gray iron, can reduce noise such as chatter, ringing and squealing, and minimize the level of applied stresses.
Gray Iron Applications
Gray iron can be cast very easily and has good machinability.
It is typically used in the following applications where strength is not the main required property:
- Weights & Counter Weights
- Powertrain Parts
- Suspension Components
- End Plates
- Valves and Fittings
- Building facades
- Table legs and bases
- Steering Knuckles
