What is Ductile Iron?
Ductile iron, also known as ductile cast iron, is a type of graphite-rich cast iron alloy for iron castings. Ductile Iron investment casting are produced for applications requiring strength, toughness, good machinability, and low cost. Ductile Iron contains spheroidal (nodular) shaped graphite, is higher strength than Gray Iron, and weighs about 10% less than steel for the same section size. Ductile Iron is a group of materials of varying grades with some common characteristics: strength and easy shaping. When it’s made, forgers control the “structural DNA” so that the precipitated graphite nodules take on a spherical shape. The spheres bond to form a microstructure that prevents cracking and gives Ductile Iron its consistency and tensile strength. Generally, it solidifies by adding tiny levels of magnesium to molten iron to create nodular iron. This equates to a strong, dependable and capable metal which lacks the brittleness of conventional cast iron.
Ductile Iron Investment Casting Advantages
Near net shape ductile iron investment casting provides the design engineer with the best combination of part design, surface hardening ability, elasticity modulus, corrosion resistance, and strength versus weight ratio. This is all accomplished while maintaining a favorable cost of manufacturing. Additionally, net shape ductile iron gives the design engineer more design freedom and provides the best overall combination of cast and post-cast characteristics. Additional advantages include but not limit to:
*Design freedom
*Cost effective
*Consistent finalized product
*Non-existent shrink rate
*Prevent the formation of external shrinkage
Ductile Iron Investment Casting in SHENGFA Hardware
Ductile iron has greater strength and ductility then gray iron. Those properties allow it to be used effectively in a wide variety of industrial applications, including pipe, automotive components, wheels, gear boxes, pump housings, machine frames for the wind-power industry, and so on.
Our ductile iron factory can make ductile iron casting in different grades, such as QT400-15, QT400-15, QT450-10, QT500-7, QT600-3, etc. Together with grey iron castings, we can supply ductile iron castings in investment casting.
