valve made by Ductile cast iron, lost wax investment casting, 0.5-100kgs capacity, flexible and elastic

Ductile iron, also called ductile cast iron, spheroidal graphite iron, or nodular cast iron, ductile iron is much more flexible and elastic, due to its nodular graphite inclusions.

Composition

A typical chemical analysis of this material:

Iron
Carbon 3.3 to 3.4%
Silicon 2.2 to 2.8%
Manganese 0.1 to 0.5%
Magnesium 0.03 to 0.05%
Phosphorus 0.005 to 0.04%
Sulfur 0.005 to 0.02%

Other elements such as copper or tin may be added to increase tensile and yield strength while simultaneously reducing elongation. Improved corrosion resistance can be achieved by replacing 15% to 30% of the iron in the alloy with varying amounts of nickel, copper, or chromium.

Applications

Much of the annual production of ductile iron is in the form of ductile iron pipe, used for water and sewer lines. Ductile iron pipe is stronger and easier to tap, requires less support and provides greater flow area compared with pipe made from other materials. In difficult terrain it can be a better choice than PVC, concrete, polyethylene, or steel pipe.

Ductile iron is specifically useful in many automotive components, where strength needs surpass that of aluminum but do not necessarily require steel. Other major industrial applications include off-highway diesel trucks, class 8 trucks, agricultural tractors, and oil well pumps.
