The Performance Benefits
ADI castings are increasingly displacing steel forgings
and castings, welded fabrications, carburised steel,
and aluminium due to superior performance:
Strength comparable to steel: Because
of its equivalent strength, nearly 80% of all cast and
forged steels can be replaced with some grade of Ductile
Iron or ADI.
Lower density than steel: The
relative weight per unit of strength of ADI allows
economy in design without loss of performance. For
a given shape, an ADI component will be 10% lighter
than steel.
"Lighter" than aluminium: ADI
is three times stronger than the best cast
or forged aluminium and weighs only 2.5 times as
much. Because it is twice as stiff, a properly designed
ADI part can replace aluminium at a weight saving. |

Weight per unit strength |
Excellent fatigue strength:
ADI's dynamic properties exceed those of forged, cast
and microalloyed steels. Unlike aluminium, ADI's endurance
limit remains nearly constant after tens of millions
of cycles.
 Noise |
|
Improved noise damping: The presence
of graphite in the ADI matrix improves noise damping,
for quieter, smoother running components.
Superior wear and abrasion resistance: ADI's
abrasion resistance exceeds that of conventionally
processed steels and irons at a lower 'bulk' hardness
level. Unlike carburised steel, which loses wear resistance
as the carburised layer is removed, ADI improves in
service. Wear resistance is superior to steel at any
given hardness level, making it ideal for earth moving
and other high abrasion applications. |
Design Assistance
To help realise the benefits of ADI in your
manufacture, we would be pleased to explore any design
opportunities with you. We can advise on all aspects
of engineering with ADI including: alloy selection,
foundry practice, dimensional stability and machining.
We can discuss potential applications and perform material
and cost analyses to help you justify selection of ADI
for your products.
We also invite you to visit our operations where we
can demonstrate the process and our ISO9001:2000 credentials.
Contact us today and find solutions with ADI.
