Factory wholesale Ductile Iron Sand Casting Company - Ductile Iron Sand Casting Pump Body – RMC Foundry Detail:

Cast Ductile Iron Sand Casting Manufacturer from China with Custom and CNC Machining Services.

Ductile iron has better strength-to-weight ratio, better machinability and higher impact value. Moreove, the ductile iron components are produced by casting process wherein better control of component shape can be achieved compared to drop forging. Thus, many a component such as crank shafts and connecting rods manufactured usually by drop forging is increasingly being replaced by ductile iron castings.

Cast iron is an iron-carbon cast alloy with other elements that is made by remelting pig iron, scrap, and other additions. For differentiation from steel and cast steel, cast iron is defined as a cast alloy with a carbon content (min 2.03%) that ensures the solidification of the final phase with a eutectic transformation.

Depending on chemical specifications, cast irons can be non- alloyed or alloyed. The range of alloyed irons is much wider, and they contain either higher amounts of common components, such as silicon and manganese, or special additions, such as nickel, chromium, aluminum, molybdenum, tungsten, copper, vana- dium, titanium, plus others. Generally speaking, the cast iron could be divided into gray iron, ducitle iron (nodular iron), white cast iron, compacted graphite iron and malleable cast iron.
