Description

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. Features include:

Low weight - density

High strength

High modulus

Excellent thermal expansion

Excellent thermal conductivity
