Advantages of Ductile Iron Castings

Ductile iron microstructure is made up of graphite nodules, which give it superior strength and ductility. It can withstand high stress loads and ultimately creating a very durable product.

When your projects demand exceptional strength, durability, and performance, ductile iron castings deliver. At Badger Foundry, our ductile iron castings range from 100 to 2,500 lbs. From simple molds to complex designs. Badger Foundry staff will conduct solidification analysis on all ductile jobs to determine modulus and design proper feed and chill to areas to ensure sound castings.  Ductile iron castings are produced for a wide range of applications, from heavy equipment, off highway, municipal, oil and gas drivetrain, compressors, agriculture and housings where strength is a critical requirement of the application.  Allow our expertise and commitment to precision delivered solutions that meet the rigorous demands of your applications.
