Aluminum-beryllium metal matrix composites combine the high modulus and low-density characteristics of beryllium with the fabrication and mechanical property behavior of aluminum. Aluminum beryllium metal matrix composites offer excellent specific stiffness and processing characteristics. This makes it more suitable for cost sensitive markets such as semi-conductor assembly and inspection equipment, avionics, and satellite electronics.

These metal matrix composites are weldable, and can be formed, machined, and brazed like conventional aluminum metal matrix composites. Aluminum beryllium metal matrix composites do not display sensitivity to machining damage and do not require etching after machining like beryllium. As aerospace systems become more weight sensitive, complex, and cost sensitive, these metal matrix composites provide benefits in many applications. When compared to metal matrix and organic composites, aluminum beryllium metal matrix composites are simpler to use and easier to fabricate.
