Abstract

AN ALUMINUM ALLOY SHEET FOR A CROSS FIN OF A HEAT EXCHANGER, CHARACTERIZED IN THAT THE SHEET CONSITS OF 0.15 TO 0.8 WTOF FE, 0.001 TO 0.02 WTOF TI, AND THE BALANCE CONSISTING OF AI AND UNAVOIDABLE IMPURITIES, THE UNAVOIDABLE IMPURITIES INCLUDING SI IN AN AMOUNT OF LESS THAN 0.15 WT, THE AMOUNT OF FE PRESENT IN SOLID SOLUTION BEING 30 TO 100 PPM; THAT THE SHEET CONSISTS OF A MID-THICKNESS ZONE CONTAINING RECRYSTALLIZED GRAINS AND A SURFACE ZONE CONSISTING OF A SUBGRAIN STRUCTURE NOT CONTAINING RECRYSTALLIZED GRAINS; AND THAT THE SHEET HAS AN ELECTRICAL CONDUCTIVITY OF 59 IACS OR MORE. A PROCESS OF PRODUCING AN ALUMINUM ALLOY SHEET FOR CROSS FIN OF A HEAT EXCHANGER, CHARACTERIZED BY COMPRISING THE STEPS OF: PROVIDING A MELT OF THE ALUMINUM ALLOY; CONTINUOUS-CASTING THE MELT TO FORM A CAST SLAB; COLD-ROLLING THE CAST SLAB AT A DRAFT OF 95OR MORE TO FORM A COLD-ROLLED SHEET; AND TEMPER-ANNEALING THE COLD-ROLLED SHEET AT A TEMPERATURE OF 250 TO 300?C FOR 4 TO 10 HOURS.(FIG. 1)
