摘要： PROBLEM TO BE SOLVED: To provide a patterned aluminum sheet in which any upper layer is not left on an exposed portion of a lower layer of a clad sheet, and a high productivity can be achieved, and a method for manufacturing the same.
SOLUTION: In the patterned aluminum sheet, an aluminum substrate of a lower layer and an aluminum perforated sheet of an upper layer having opening parts consist of a clad sheet integrated by the clad rolling, and a pattern is formed over the entire surface of the clad sheet by providing an anodically oxidized film of different tone on the surface of the perforated sheet and the surface of the substrate exposed in the opening parts. The method for manufacturing the patterned aluminum sheet includes a step of superposing the aluminum substrate of the lower layer on the aluminum perforated sheet of the upper layer having opening parts in advance, and performing the clad-rolling of the superposed sheets, and a step of forming a pattern over the entire surface of the clad sheet by expressing different tone on the surface of the perforated sheet and the surface of the aluminum substrate exposed within the opening parts by performing the anodic oxidation treatment of the obtained clad sheet.

摘要： PROBLEM TO BE SOLVED: To provide a vessel for electromagnetic cooking which can be utilized easily even for the aged, or the like, and is neither peeled nor deformed even after long-period use by reducing the weight of the aluminum vessel for electromagnetic cooking in which stainless steel is clad. SOLUTION: A bottom plate is produced by carrying out high-temperature compressing and molding such as burning of a mixture of fine aluminum (aluminum is made into powder by atomization, for example,) and a flat fine ferromagnetic substance (stainless steel, for example). This bottom plate is fixed on the bottom of the outer face of a vessel body of the aluminum vessel for electromagnetic cooking by means of brazing or press-welding. Thus, the bottom plate to be heat-generated under electromagnetic induction is hardly affected by a thermal expansion difference and the aluminum vessel for electromagnetic cooking to be strongly coupled is obtained.
