Neenah Enterprises foundries produce industrial parts and components in a variety of materials to meet any design specifications. Below is a brief rundown of the materials we work in and what differentiates them from one another. NEI sets the standard in excellence and quality.

Gray Iron (up to 2,000 lbs.)

Gray iron is the most commonly used cast iron in the world today. Gray iron has small amounts of carbon and silicon present in the metal, with the remainder being iron. Gray iron’s compressive strength is comparable to low and medium carbon steel.

Ductile Iron (up to 2,000 lbs.)

Ductile iron adds alloying elements to the iron to provide added strength and integrity.

Austempered Ductile Iron

Austempered Ductile Iron (ADI) is ductile cast iron, heat-treated using a tightly controlled process that produces a unique microstructure. ADI is available in six ASTM standard grades, covering a wide range of strength and hardness characteristics.

Micro-alloyed steel forgings (up to 110 lbs.)

Ferrous and micro-alloy steel forgings provide superior strength and toughness by aligning the grain flow with the shape of the part.
