USMA offers a family of beryllium and beryllium oxide metal matrix composites (MMC) that are made to an electronic-grade and classified as E-Materials. These Be/BeO MMCs are made for designers who need high strength, good thermal conductivity and high modulus . Our beryllium and beryllium oxide metal matrix composites (MMC) also have a lower coefficient of thermal expansion than beryllium.
BE / BEO MMC E-MATERIAL ADVANTAGES
Our beryllium and beryllium oxide metal matrix composites provide superior performance for several application criteria including:
Low weight-density
High strength
High modulus
Excellent thermal expansion
Excellent thermal conductivity
Beryllium and beryllium oxide metal matrix composites (MMC) HIGH MODULUS & THERMAL ADVANTAGE
Beryllium and beryllium oxide metal matrix composites provide outstanding stiffness-to-weight ratios with thermal cycle reliability over a broad temperature range. The high elastic modulus of helps absorb vibrations, lowering the material fatigue of attached modules and wire bonds.
Beryllium and beryllium oxide metal matrix composites (MMC) offer high thermal conductivity and low thermal expansion. Their thermal expansion can be adjusted to match that of other materials, such as silicon, gallium arsenide and various ceramics.
Beryllium and beryllium oxide metal matrix composites (MMC) MARKETS & APPLICATIONS
Since our MMCs offer low weight, high modulus and high strength, they are used in several applications and markets including:
Microelectronics-electronic heat sinks and chill plates.
Aerospace-aerospace applications and components.
Semiconductor-power devices
