Publication number: 20060260724Abstract: An aluminum alloy-based extruded flat tube having the increased proof strength and pressure-resistant strength is disclosed. An aluminum alloy-based extruded multi-path flat tube that is obtained by extruding an aluminum alloy billet is subjected to the low strain working at the low strain of 2% to 15% prior to the brazing process. After the flat tube is brazed, it may have the organization that includes the surface layer containing equal to 5% or more than 5% of non-recrystallized grains and the inner layer containing equal to 30% or more than 30% of recrystallized grains. The strain may be expressed as (1?H/H0) * 100%, for example, in which H0 refers to the height of the flat tube prior to low strain working process, and H refers to the height of the flat tube after the low strain working process is completed. The proof strength can be increased by the non-recrystallized grains contained in the surface layer 1a and in the surface layer 2a in the path of fluid passage.Type: ApplicationFiled: May 5, 2006Publication date: November 23, 2006Inventors: Yasunori Hyogo, Masaya Katsumata, Masami Asano
