Electronic Materials by Materion Brush Beryllium & Composites are a metal matrix composite of beryllium and beryllium oxide. E-Materials are prepared by impact grinding to powder. They are then canned, degassed, and HiP'd into a standard stock block (15 x 20 x21).
The stock block is sliced into cards, which are then cut to specified sizes, lapped and machined into the final sizes. The parts can then be plated in accordance with final termination specification.
