ABSTRACT:
A honeycomb core diaphragm is described, which contains a honeycomb core made from a thin plate of beryllium or beryllium alloy which is produced by a super-rapid cooling method. Since the thin plate of beryllium or its alloy has a high modulus of elasticity and low density and, furthermore, is easily moldable, it can be easily molded to produce a honeycomb core having a high modulus of elasticity and low density.
