We bring over 140 years of experience to each and every one of our partnerships. Neenah Enterprises, Inc. (NEI), is a key component provider for many of the world’s leading manufacturing companies. NEI designs and builds cast iron parts for several industries – working alongside our clients every step of the way to bring their vision to life. Because at NEI, we are more than a supplier – we are a partner.
A special area of expertise for NEI is Austempered Ductile Iron (ADI). ADI is a range of heat-treated ductile cast irons with high strength, excellent toughness, good fatigue properties, and superior wear characteristics. It’s tensile, and yield strengths are at least twice that of standard ductile iron, making ADI a cost-effective replacement for structural steels and materials used in high-wear applications. NEI offers a unique foundry solution to ADI by operating our own in-house salt-to-salt austempering line within ACP.
NEI is committed to providing more than just products to our customers. We are committed to building partnerships. Our experienced and responsive engineering staff can assist your engineers in designing a product that adapts to the constraints of the casting and forging industries, saving time and money.

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.
NEI is more than a supplier; we are an integral partner who understands the demands of managing multiple supplier tiers in preparation for a successful product launch. Utilizing our established APQP and Tier 1 Management tools and processes, we take the hassle out of managing multiple layers of suppliers and ensure high-quality products and on-time delivery through product development and production cycles.
