Ductile Iron Casting

Ningbo Supreme Machinery Co., Ltd is a professional ductile Iron casting manufacturer and supplier in China.

We have been in this line for more than 25 years, products are mainly exported to USA, Australia, Germany, Italy, Japan, South Africa, etc.

What is Ductile Iron Casting?

It can be obtained by spheroidizing treatment of molten iron of grey iron , and the precipitated graphite is spherical, so we call it ductile iron for briefly. It has higher strength, better toughness and plasticity than common grey cast iron, mainly used in the manufacturing of internal combustion engines, auto spare parts and agricultural machinery.
