Title:
MANUFACTURE OF HIGH STRENGTH ALUMINUM ALLOY CLAD FIN STOCK FOR HEAT EXCHANGER
Document Type and Number:
Japanese Patent JPH05305307
Kind Code:
A
Abstract:
PURPOSE: To provide a method for inexpensively manufacturing Al alloy clad fin stocks having high temperature buckling resistance and high strength after brazing.
CONSTITUTION: Homogenization treatment of the specified Al-Mn-Si Al base alloy ingot is executed at the temperature of 400-560°C, and the ingot is heated at the temperature of 400-560°C to start hot rolling, and after hot rolling is completed at the temperature of 300°C or lower, cold rolling is executed at the draft of 40% or less. After annealing at the temperature between 180°C-240°C, the cold finish rolling is further executed at the draft of 5-50%.
