Materials

From raw material to finished part

Our expertise in material compositions is our capital. We know exactly what mix of steel, pig iron and many different alloy constituents is right for each final product. The choice of materials as well as the sound process parameters is crucial to the quality and characteristics of our products.

Extensive data-base for centrifugal casting materials

Together with our customers, we have developed a range of material compositions to ensure the best properties in continuous operation. We have an extensive database of centrifugal casting alloys as a basis for calculation when drawing up design plans.

Our materials experts oversee every stage, from the casting process to the finished product and also the subsequent operation in machines and engines. The various highly specialised testing processes begin in the foundry laboratory at the melt and continue through mechanical production to the finished product.

Materials used by M. Jürgensen

Cast iron with lamellar graphite

This is not only the oldest iron-based cast material, but also the one most widely used to this day. Much of the carbon solidifies as graphite in lamellar form when cast.

The advantages of our centrifugally cast iron are excellent damping properties, good thermal conductivity, outstanding antifrictional properties, good resistance to wear and corrosion and an extremely high compressive strength at the various tensile strength ratings to which the material may be adapted.

Furthermore centrifugally casting considerably advances fatigue strength values.

Cast iron with nodular graphite

In this type of cast iron, the graphite takes a nodular shape. This has the advantage that the material possesses high tensile strength, fatigue strength and ductility.

Austenitic cast iron with lamellar graphite

Unlike ordinary cast iron with lamellar graphite, the basic material in austenitic cast iron with lamellar graphite consists of austenite. So this material has all the positive properties of cast iron made with lamellar graphite: excellent damping properties, good thermal conductivity, and an extremely high compressive strength at the various tensile strength ratings. In addition, this material is also very resistant against corrosion caused by acid, alkaline and saline materials or other aggressive agents. This makes it ideal for use in environments where this is an issue.

Austenitic cast iron with nodular graphite

Compared with austenitic cast iron with lamellar graphite, austenitic cast iron with nodular graphite has considerably greater tensile strength and ductility. Its austenitic matrix makes this material an ideal choice for applications that require good corrosion resistance against acidic, alkaline, saline or other aggressive agents, and high mechanical loads.

Composite casting / Bimetallic casting

In composite casting we use the centrifugal casting process to produce a shell structure of the materials. This creates a distinct composite zone where one material passes into the other. Outside this transition, however, the material properties are unaffected. The transition zone is compact, this means that there are no junctions that could act as barriers to heat conduction or as starting points for fatigue fractures.

In this way we combine the positive properties of two materials. We manufacture, in series, highly loadable composite / bimetallic liners. They consist of high-strength cast iron with nodular graphite on the outside and lamellar cast iron inside to ensure good running characteristics.

We have developed a special, patented process of sectional bimetallic casting. It involves casting an extremely wear-resistant material only in areas that will be under extreme wear and tear later in operation. The other cylinder running surface of the liner remains unaffected.

We would be pleased to answer your questions about centrifugal casting and the application spectrum for engine and machine components. Our customer support starts with the design phase, continued by prototypes which are followed by serial production. Finally, we stay in touch with our excellent after-sales service.
