摘要： The method manufactures a hermetic sealing lid member used for an electronic component housing package including an electronic component arrangement member on which an electronic component is arranged. The method includes forming a clad material in which a silver brazing layer that contains Ag and Cu and a first Fe layer arranged on the silver brazing layer and made of Fe or an Fe alloy are bonded to each other by roll-bonding a silver brazing plate that contains Ag and Cu and a first Fe plate made of Fe or an Fe alloy to each other and performing first heat treatment for diffusion annealing; softening the clad material by performing second heat treatment; and forming the hermetic sealing lid member in a box shape including a recess portion by bending the softened clad material.

摘要： A process may be used to produce a composite material in a rolling plant. The process may involve providing a first workpiece and a second workpiece, which workpieces are configured in the form of a temporary composite. The process may further involve producing a planar connection between the first and second workpieces in the temporary composite by prerolling. Still further, the process may involve rolling, in particular hot rolling, the temporary composite to form the composite material after the planar connection has been produced by prerolling. The process may also involve heating the temporary composite before and/or after the prerolling.

摘要： A stiff, lightweight metal laminate includes a first continuous metal layer, a second continuous metal layer, and a reduced density metal core layer disposed between the first and second continuous metal layers. The reduced density metal core layer comprises a core metal and has an average density that is less than the density of the core metal. Planar metallurgical bonds secure the first and second continuous metal layers to the reduced density metal core layer. The metal laminate may be manufactured by press rolling the reduced density metal core layer sandwiched between the two continuous metal layers, after removing or overcoating the native oxide layer on each layer surface that contacts another layer in the metal laminate.
