Abstract

PURPOSE:To increase the thickness and the rigidity further, by laminating thin film made of the material in which the Young's modulus is 1.0X10<12> dyn/cm<2> or more, on the one side at least made of magnesium or magnesium alloy. CONSTITUTION:Magnesium or magnesium alloy is used for the base, and the material lime Be, B, SiC in which the Young's modulus is 1.0X10<12> dyn/cm<2> or more is laminated on one side at least. Taking the weight of the diaphragm plate the same, the diaphragm plate laminating Be on Mg-Li alloy has very greater value of Eh<3>/12 (where; E is the Young's modulus and h is the height) which is the gist of the rigidity as actual diaphragm plate.
