Title (EN) CLAD METAL SHEET AND HEAT EXCHANGER TUBING ETC. MADE THEREFROM
(FR) TÔLE REVÊTUE ET TUBES D'ÉCHANGEURS DE CHALEUR ET AUTRES COMPOSANTS FABRIQUÉS À PARTIR DE CETTE TÔLE
Abstract:
(EN) The exemplary embodiments relate to a multilayer aluminum alloy sheet material suitable for fabrication into coolant-conveying tubes, headers and the like used for heat exchangers, and to the tubes and headers, etc., fabricated from the sheet. The multi-layer metal sheet has a core layer of aluminum alloy having first and second sides. The first side has an interlayer made of a Zn-containing aluminum alloy positioned between a Zn-containing outer layer and the core layer. The alloy of the outer layer is more electronegative than the alloy of the interlayer. The alloy of the interlayer is preferably more electronegative than the alloy of the core layer. The first side clad in this way is the side intended for exposure to the coolant, and provides good resistance to corrosion and erosion.
(FR) La présente invention concerne un matériau stratifié multicouche à base d'alliage d'aluminium convenant pour la fabrication de tubes de transport de réfrigérant, de collecteurs, etc. Cette tôle multicouche comporte une couche de cœur en alliage d'aluminium avec un premier et un deuxième côté. Le premier côté comporte une couche intercalaire en alliage d'aluminium contenant du zinc positionnée entre une couche externe contenant du zinc et la couche de cœur. L'alliage de la couche externe est plus électronégatif que celui de la couche intercalaire. L'alliage de la couche intercalaire est de préférence plus électronégatif que celui de la couche de cœur. Le revêtement du premier côté est destiné à être exposé au réfrigérant, et apporte une bonne résistance à la corrosion et à l'érosion.
