Abstract

PURPOSE:To obtain thick diaphragm and good workability, by forming the diaphragm made of alloy which consists of magnesium and >=10wt% lithium. CONSTITUTION:Diaphragm consists of magnesium and lithium at least, and the alloy contains >=10wt% lithium. In case when the diaphragm of magnesium-lithium is molded in a form of diaphragm, provides remarkably high Eh<3>/12 value which is the standard of rigidity in real using condition as compared with the value of the diaphragm made of titanium and aluminum. Further, extensibility is also added by using alloy which provides lithium having good extensibility.
