Who We Are: The Ductile Iron Marketing Group is a nonprofit organization that disseminates technical information to design and materials engineers and purchasers of castings and mechanical components. We are capable of answering most questions about Ductile Iron and it’s uses.
Since 1948, Ductile Iron castings have proven to be an effective, lower cost alternative to malleable iron castings, steel forgings and steel fabrications. It appears Ductile Iron was invented with the designer in mind. High Tensile Strength, yield strength and elongation combine to give Ductile Iron a superior strength to weight ratio that adds up to more strength for less expense.
Please enjoy the Ductile Iron Marketing Group Web Site. Feel free to view the “Ductile Iron Design Engineers Digest“, a 48 page summary of Ductile Iron properties, applications and design ideas. Also online is our 2 page “Why Convert to Ductile Iron,” “Designs in Ductile Iron” and “Ductile Iron Data,” which gives complete property and specifications information. Hard copies are also available (see below).
