AlBeMet® is a metal matrix composite developed by Materion that combines the high modulus and low density characteristics of beryllium with the fabrication and mechanical property behaviors of aluminum. This material offers significant performance advantages in certain applications when compared to steel, aluminum and common aluminum metal matrix composites. Its properties allow for greater design flexibility and specific stiffness making AlBeMet the perfect material choice for applications in aviation electronics, inspection equipment for semiconductor assembly, and optical and satellite structures.

AlBeMet does not display sensitivity to machining damage and does not require etching after machining. When compared to metal matrix and organic composites, beryllium aluminum metal matrix composites are simpler to use and easier to fabricate. Typical aluminum coating technologies can be applied to AlBeMet. Beryllium aluminum’s performance-to-cost relationship has allowed Materion’s costumers to successfully use AlBeMet as a replacement for traditional aluminum in applications that require beryllium aluminum’s greater property strengths.


AlBeMet improves line-of-sight distance and reduces jitter in optical structures. Its properties allow designers to reduce system size, minimize stress from vibrations and increase the fatigue life of electronic packages while improving performance. Because of its excellent stiffness-to-weight ratio, the product is used extensively in optical and structural components in aircraft and satellite and commercial applications. It’s currently being used in the U.S. Military’s F-35 Lightning ll, F-16 and the Boeing AH-64 Apache as well as other military aircraft. To date, AlBeMet has been used in more than 150 satellites currently orbiting in space.

AlBeMet is a powder-metallurgy alloy offered in three different forms: hot isostatic pressed (HIP), extruded (EXT) and rolled sheet (RS). It can be fabricated using the same techniques and fabrication tooling used for aluminum alloys.

This versatile metal matrix composite is selected when weight and inertia factors exceed those of lower cost aluminum. With its low mass, it can be driven through the scanning cycle much faster, with lower power requirements. AlBeMet is certified to AMS7911, AMS7913 and AMS7912
