Grey Iron

Below is a list of Grey Iron manufacturers from St. Paul, Minnesota.

Grey iron is a type of metal often used in castings. In the past, grey iron was known as cast iron; however, cast iron is now made out of iron-carbon alloys that have a higher level of ductility. Because of the low ductile properties of grey iron, high levels of tensile stress will result in its breaking or fracture.
