For 50 years, DuraBar® cast iron has been a trusted solution across industries that depend on precision and performance.

Its consistent structure and reliable machinability have made it a go-to material for engineers looking to reduce variability and improve efficiency.

Decades later, that same consistency continues to support modern manufacturing.

When comparing materials, performance is the only metric that matters.

In the right applications, Austempered Ductile Iron (ADI) can deliver:
>Comparable strength to steel
>Improved wear resistance
>Reduced weight

But the advantage isn’t just in the material. It’s in how it’s applied. Choosing between ADI and steel isn’t about substitution. It’s about understanding load, wear, and operating conditions and selecting the material that performs accordingly.

At Charter Casting, we work alongside engineers early to evaluate those decisions and optimize performance before production begins.

Strength doesn’t happen by chance. It starts with material selection.
Process discipline. Engineering decisions made early.

At Charter Casting, Strength From Within means performance is built into every casting, long before it reaches the field.

It guides how we engineer, how we solve problems, and how we support our customers.

Because what’s beneath the surface isn’t hidden. It’s what determines how everything performs.

For more than 50 years, DuraBar® products have defined the standard for continuous cast iron bar.

In applications where consistency is non-negotiable, it delivers predictable machinability, uniform structure, and repeatable performance from run to run.

That legacy isn’t built on time. It’s built on disciplined process control, controlled chemistry, and results that hold up in real-world production.

Because consistency isn’t claimed. It’s engineered.

Austempered Ductile Iron (ADI) offers a unique combination of strength, wear resistance, and weight reduction that often outperforming steel in the right applications.

The challenge isn’t capability.
It’s knowing where and why to apply it.

At Charter Casting, we work alongside engineers early in the design process to evaluate material selection, identify where ADI can replace traditional materials, and improve performance without adding complexity.

Because the right material choice doesn’t just meet requirements.
It changes outcomes.

Not every solution can be simplified. Some applications demand large, complex castings that perform under pressure. Literally and figuratively.

At Charter Casting, we produce iron castings designed for tight specifications, demanding environments, and consistent performance at scale.

Because when complexity is engineered correctly, performance becomes predictable.

Last week we welcomed Congressman Tony Wied to our Shawano facility.

The visit was a great opportunity to discuss manufacturing’s role in supporting local communities, creating strong career opportunities, and driving economic growth. Congressman Wied met with employees throughout the tour and engaged in conversations about our operations, culture, environmental stewardship, and continued investment in a safe, modern workplace.

We also shared how Charter Casting’s Strength from Within is driven by our people and specialized capabilities, helping us deliver innovative solutions for customers and support the industries that help feed, build, and defend America.

We appreciate the time Congressman Wied spent learning more about our operations and the people who make them successful every day.

The work we do starts with the people behind it.

At Charter Casting, that means engineers, operators, and problem-solvers who bring technical expertise and real-world experience to every challenge.

From early design collaboration to production support, that mindset shapes how we approach every project , always asking better questions, working through complexity, and focusing on outcomes that perform.

Because strong results don’t come from process alone.
They come from the people driving it.

As the industry evaluates alternatives to HF-1 steel, one material gaining attention is austempered ductile iron (ADI).

ADI offers a different approach to manufacturing. Instead of requiring complex forging processes, ADI components can be cast close to their final shape, reducing raw material waste, machining requirements, and overall energy use in production.

This manufacturing advantage also allows production to scale more efficiently using existing foundry infrastructure.

At the same time, ADI delivers strong mechanical performance. Through precise heat treatment, its microstructure can achieve tensile strengths comparable to, and in some cases exceeding, heat-treated steels.

For manufacturers looking to balance performance, cost efficiency, and production capacity, ADI represents a compelling material option worth exploring.
