Home Products Metal Matrix Composites E-Materials 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 Talk with Materion engineers to discuss how our E-Material metal matrix composites can improve thermal management and provide high modulus for your electronics and semiconductor applications.
