aluminum alloy with improved penetration resistance for heat exchangers extrusion tube and fin material with improved penetration resistance comprising the same and the heat exchanger constructed the same

摘要

The present invention relates to an aluminum alloy for a heat exchanger having improved resistance to penetration which further contains copper (Cu), silicon (Si) and iron (Fe) at a predetermined concentration or less and further contains zirconium (Zr) and aluminum The present invention relates to an aluminum extruded tube, a fin material, and a heat exchanger including the aluminum extruded tube and the fin material. The aluminum extruded tube has improved through resistance, And an aluminum alloy composition in which extrusion resistance is maintained at a level of conventional A1070, an aluminum extrusion tube and a fin material for the heat exchanger having improved penetration resistance, and a heat exchanger composed of the same.;
