Title (EN) COOKWARE WITH COPPER BONDED LAYER
(FR) USTENSILE DE CUISSON AVEC COUCHE LIÉE AU CUIVRE
Abstract:
(EN) Provided is an article of cookware and a method of making the same. The cookware has at least one stainless steel layer and at least one copper layer metallurgically bonded directly to the at least one stainless steel layer via solid state bonding. The at least one stainless steel layer may be a ferritic stainless steel layer, and the at least one copper layer may be a grain stabilized copper. The at least one stainless steel layer may be made from a 400 series stainless steel, such as a 436 stainless steel alloy, a 439 stainless steel alloy, or a 444 stainless steel alloy. The at least one copper layer may be made from a high purity, oxygen free copper alloy, such as a C101 copper alloy, a C102 copper alloy, or a C107 copper alloy.
(FR) L'invention concerne un article d'ustensile de cuisson et son procédé de fabrication. L'ustensile de cuisson comporte au moins une couche d'acier inoxydable et au moins une couche de cuivre directement liée de manière métallurgique à l'au moins une couche d'acier inoxydable par l'intermédiaire d'une liaison à l'état solide. L'au moins une couche d'acier inoxydable peut être une couche d'acier inoxydable ferritique, et l'au moins une couche de cuivre peut être un cuivre à grains stabilisés. L'au moins une couche d'acier inoxydable peut être constituée d'un acier inoxydable de la série 400, tel qu'un alliage d'acier inoxydable 436, un alliage d'acier inoxydable 439 ou un alliage d'acier inoxydable 444. L'au moins une couche de cuivre peut être constituée d'un alliage de cuivre de haute pureté, sans oxygène, tel qu'un alliage de cuivre C101, un alliage de cuivre C102 ou un alliage de cuivre C107.
