A new material for a changing world

Today, industrial applications demand material performance that is faster, lighter and more economical. Starmet's new alloy, Beralcast® meets these demands for greater performance.

Beralcast's®, our family of beryllium-aluminum alloys have advanced properties that optimize the attributes of each material. Beryllium provides the strength and stiffness while aluminum offers the ductility and toughness. Among its superior performance characteristics are light weight, dimensional stability, stiffness, superior vibration damping and workability.

3 1/2 times stiffer and 22% lighter than aluminum, Beralcast® is ideally suited for demanding aerospace and commercial applications.

Through investment casting Beralcast® can be formed into complex shapes that require little or no machining and processing. 22% lighter and 31/2 times stiffer than conventional aluminum castings, Beralcast® has enabled engineers to achieve component weight savings of up to fifty percent. Beralcast® is the choice for weight critical structural applications such as optical systems, advanced guidance components for satellites and structural components for U.S. Army helicopters.

Beralcast® is also being used in the electronics, semi-conductor and sporting goods industries for applications in computer disk drive components, motion control equipment and golf clubs, respectively.
