Ductile Iron Casting Foundry

Strong Enough for Shaping, Tough Enough for Long-Term

Ductile iron is a ferrous alloy and increases the durability, reliability, and safety of precision cast components compared to other ferrous and non-ferrous alloys. One of the primary applications of ductile iron is in the production of precision cast compnents, which can be achieved through the use of a ductile iron foundry. Most cast irons are brittle, but due to its nodular graphite inclusions, ductile iron is much more resistant to impact and fatigue. Ductile iron is a flexible material that can serve as a substitute for wrought iron when producing bearing housing due to its remarkable durability and resilience. It is also a preferred choice for fountain foundries as it can be easily cast and has high resistance to rusting.

Characteristics of ductile iron include:

High Strength
High Ductility - ability to deform under tensile stress
Resistance to Shock

Advantages of Ductile Iron Casting

Because our process allows metal to anneal, precision cast ductile iron can be bent, twisted or deformed without fracturing. When compared to carbon steel and gray iron pipe, ductile iron pipe offers several advantages such as higher durability, improved resistance to corrosion, and better flexibility, making it a popular choice in various industries. Ductile iron shares the strength and durability found in typical grades of steel, but shares the design flexibility and low-cost characteristics of gray iron.

Characteristics of Ductile Iron

Ductility	Ductile iron is one of the most ductile of all types of cast iron.
Elasticity	Modulous of elasticity of ductile iron is higher than gray iron and a little lower than cast steel.
Yield Strength	Yield strength of ductile iron is higher than gray iron and some grades of cast steel. High yield strength creates a high safety factor in thermal stress or load bearing applications. High modulous of elasticity and high yield strength provides a high safety factor.
Tensile Strength	The cast strength of ductile iron starts around 60,000 psi and tops out around 100,000 psi.
Corrosion Resistance	The corrosion resistance of ductile iron is at least equal to cast steel. Advantages include its neutrality to alkaline brines. Ductile iron also shows resistance to concentrated sulfuric acid and steam condensate.
Heat Resistance	High temperature strength of ductile iron is comparable to cast steel at around 800°F.
Impact Resistance	Ductile iron has a good impact resistance and is dependant on the degree of ferritization in the microstructure. For example, if the ductile iron is highly ferritic, it will have a high impact resistance rating.
Wear Resistance	Wear resistance of ductile iron is comparable to cast gray iron.

Versatile Material for Industrial Applications

Besides being extremely durable, ductile iron casting is versatile in its own way. Suitable for several industries, ductile iron is the perfect material for casting. Precision iron casting works well for the following applications:

Wind power
Water & sewer
Automotive
