QUINTET JUNCTION CLAD PLATE AND METHOD THEREFOR

摘要

PURPOSE: A quintet junction clad plate is provided to prevent a surface of a copper from being revealed, thereby solving a problem of endurance against an oxidation caused by the contact with food and air. CONSTITUTION: The clad plate having a junction of a stainless plate, an aluminum plate and a copper plate, comprises: a stainless plate(11); an aluminum plate(12) processed by brushing on its both sides; a copper plate(13) processed by brushing on its both sides, each plates being piled in series in the form of a quintet junction and being jointed by rolling process; a first oxide layer(11) between the stainless plate(11) and the aluminum plate(12), the first oxide layer(11) being formed by junction of both oxide layers on the surfaces of the stainless plate(11) and the aluminum plate(12); and a second oxide layer(12) formed by an oxide layer on the surface of the aluminum plate(12).
