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

This material data has been provided by Materion Brush GmbH.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
