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.
Ductile Iron Casting Advantage
high strength, ductility, and wear resistance
Lower costs than that of steel casting
Higher production rate
Dimensional accuracy, clear external outline
Smooth surface, good quality
Energy saving, labor saving.

Supreme Machinery has has been manufacturing Nodular Cast Iron Castings.
These parts are widely used for automotive, motorcycle, agricultural machinery.
Nodular cast iron is a type of cast iron that has high strength and ductility due to the presence of nodules or spherical graphite in its microstructure. Nodular cast iron casting is a common casting process used to manufacture parts that require high strength and wear resistance.
ASTM A536 65-45-12 Ductile Iron Castings is a ductile iron casting specification that offers high strength, ductility, and impact resistance. This specification describes a specific grade of ductile iron that contains 65,000 psi minimum tensile strength, 45,000 psi minimum yield strength, and 12% minimum elongation.
