Ductile iron receives treatment with magnesium before the casting process to produce a very strong, impact resistant and durable metal suitable for applications requiring both tensile strength and toughness.
It typically possesses higher strength than gray iron, weighs about 10% less than steel of comparable size and weight, and displays superior corrosion resistance compared to most other cast iron products.
Ductile iron is suitable for the production of components of a very wide weight range, from several grams to hundreds of tons. It may replace aluminum or cast and forged steel in some situations, which is why it’s used extensively in the automotive industry.
Ductile Iron possesses the following characteristics:
