HIGH-PERFORMANCE ALUMINUM MATERIAL FOR AIR CONDITIONER CONNECTING PIPE AND PREPARATION METHOD THEREFOR

摘要

Disclosed are a preparation method for a high-performance aluminum material and an aluminum material prepared by the method, and an air conditioner connecting pipe prepared by the high-performance aluminum material. The method comprises the steps of raw material selection and smelting, aluminum liquid component analysis, alloying treatment, refining, slag skimming, component adjustment, external refining and slag removal, continuous casting, continuous rolling and annealing treatment. The high-performance aluminum material has good corrosion resistance, fatigue resistance and tensile strength, which all meet the requirements of aluminum alloy materials of air conditioner connectors for extrusion forming.
