- Relatively inexpensive
- Easier to cast due to expansion
- Grey iron also has unique properties which are useful for applications with sliding surfaces like hydraulic pistons.
- Free graphite within the structure acts as a lubricant and aids machining.
- Excellent damping and wear characteristics.
- Used where tensile strength and ductility are non-critical:
- Engine blocks
- Valve bodies
Cheaper than other materials
- High tensile strength and ductility compared to grey iron.
- Tensile strength and ductility can vary across the range of grades allowing for irons to be suitable for a wide range of applications:
- Automotive components
- Load bearing applications
- Replaces steel for many applications and achieves a significant cost saving
- Easy to machine
- Corrosion resistant compared to other ferrous metals.
High tensile strength
- Recent development in iron metallurgy
- Controlled heat treatment cycle results in iron with a very high tensile strength and hardness
- Lighter and cheaper than mild steel while possessing improved mechanical properties
- Stronger than aluminium per unit weight
- Excellent fatigue strength
- Abrasion resistance
- Good noise dampening
Excellent hardness and strength
- Silicon molybdenum alloy iron
- Resists oxidisation at high temperature
- It is frequently used for turbine housings and exhaust manifolds in modern high performance engines
Perfect for high temperatures
- Nickel alloy iron
- Resistant to oxidisation at high temperatures
- Resistant to corrosion in harsh chemical environments
