The Sioux Indian Nation occupied the Mississippi River Valley in 1885, the year Alliant Castings began as Diamond Huller to manufacture feed grinders and corn shellers for the escalating agricultural industry of the Upper Midwest.

100 years later, our focus is on the manufacturing of abrasion resistant iron alloy castings for worldwide distribution.

Our dedication to continual updates in casting technology, alloys, and equipment allows us to deliver the highest quality castings our industry can provide.
