What is ductile iron?

We manufacture our high-performance range of products from ductile iron. Ductile iron is a unique form of graphite-rich cast iron which has been treated before the casting process to produce an exceptionally strong and durable material with high impact resistance.

It is also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spheroidal graphite cast iron and SG iron. It has a much superior strength to weight ratio than traditional grey cast iron.

This combination of properties allows us to design and produce our innovative features and make significant weight savings that could not be achieved with less sophisticated materials.
