Ductile iron is what?(of)
If you want to for chemical analysis of nodular cast iron, this is what you will usually find:
Iron ~ 94%
Carbon 3.2 -3.60%
Silicon 2.2 -2.8%

Manganese 0.1- 0.2%
Magnesium 0.03- 0.04%
P 0.005- 0.04%
Sulfur 0.005- 0.02%
Copper < = 0.40%
In order to improve the strength of the nodular cast iron, can add additional tin or copper.In order to improve the corrosion resistance, copper, nickel and chromium alternative to 15-30% of iron.

Common level of nodular cast iron:

Although there are many different nodular cast iron specifications, foundry usually provide three kinds of common brand;

Ductile iron castings:
Nodular cast iron was invented by the middle of the twentieth century synthesis of metal material, is a kind of used in the manufacture of cast iron.Cast iron technology of molten iron and metal material, has the ductility.

Ductile iron process must start from the production of ductile iron, nodular cast iron is formed by adding small amounts of other elements into the iron, so that the carbon ball instead of thin sheet.This enables the material to without destroying situation to change.Usually, nodular cast iron has a higher tensile strength than that of gray cast iron, grey cast iron is traditionally used in the manufacture of iron cast iron products.Nodular cast iron, as the name implies, than the traditional more malleable iron material, the traditional iron materials tend to be more brittle, easy to fracture under high tensile stress.Ductile iron is usually used in the manufacture of cast iron pipe, the use of the water and sewer.Nodular cast iron used in many various applications in different industries.These industries include, but are not limited to agriculture, automobile, irrigation, ventilation, hydraulic pressure.


We can provide:
Material: alloy steel, carbon steel, stainless steel, malleable cast iron, grey cast iron, ductile iron, aluminum bronze, etc
