Ductile Iron Castings
Ductile Iron combines the castability, machinability, and corrosion resistance of gray iron with the high strength, ductility, and hardenability of steel.
CPM Industries has over 60 years of experience in producing Ductile Iron Castings. With our in-house Pattern and Machine Shop, we handle your project from start to finish, eliminating the need to coordinate between foundries and machine shops. We can produce castings up to 2500 lbs and handle orders from prototypes to annual runs of up to 2500 units.
