HIGH STRENGTH AND HIGH CORROSION-RESISTANT ALUMINUM ALLOY FOR HEAT EXCHANGER TUBE AND HEAT EXCHANGER TUBE PREPARED FROM THE SAME

摘要

The present invention relates to an aluminum alloy having a high strength and a high resistance to corrosion for a heat exchanger piping, and the heat exchanger piping manufactured from the same. More specifically, the present invention relates to an aluminum alloy and heat exchanger piping manufactured from the same wherein the aluminum alloy satisfying all of the resistance required as a heat exchanger piping alloy, the resistance to corrosion, and the extrusion property; a tradeoff existing between the same and the strength; the aluminum alloy being capable of minimizing or avoiding deformation of the alloy structure before and after high-temperature heat treatment; and the aluminum alloy reducing manufacturing costs.
