ELECTRONIC-GRADE BERYLLIUM & BERYLLIUM OXIDE COMPOSITES


Materion 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 E-Materials 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

E-MATERIAL 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.

E-Materials 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.

E-MATERIAL 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

E-MATERIAL GRADES AVAILABLE

Our beryllium and beryllium oxide metal matrix composites are available in different grades, including:

E-40:

  • Beryllium Oxide (weight %) 49.50% min., 54.80% max.

E-60:

  • Beryllium Oxide (weight %) 69.4% min., 73.2% max.

Download our E-material spec sheet for more on the chemistry and physical properties.

FORMS AVAILABLE

E-Materials are powder-based products made by combining beryllium and beryllium oxide into a homogeneous mixture. The beryllium based metal matrix composites are prepared by impact grinding and then hot isostatic pressing to form stock blocks that are cut to customer requirements.

E-Materials are available in:

  • Bars
  • Slurry Saw Cut Cards
