Embodiment Construction

[0021] The invention provides an AA3XXX aluminum-manganese series aluminum alloy brazing sheet material with good formability and brazing performance and a manufacturing method thereof. This sheet can be used for radiator components such as evaporators, main boards, side panels, intercoolers and oil coolers.

[0022] The manufacturing method of aluminum alloy brazing sheet material according to the present invention comprises the following steps that are carried out in sequence:

[0023] a) cast aluminum alloy ingot;

[0024] b) Homogenize the ingot, then cool and perform conventional face milling;

[0025] c) performing a single-sided or double-sided composite aluminum-silicon solder layer on the ingot to form a composite material;

[0026] d) heating the compound;

[0027] e) hot rolling and cold rolling the heated composite material to form a cold rolled material having a first thickness;

[0028] f) performing complete softening annealing on the cold-rolled material; a...

Abstract

The invention discloses an aluminum alloy brazing sheet and a manufacturing method thereof as well as a radiator part manufactured by using the aluminum alloy brazing sheet. The method comprises the following steps: casting an aluminum alloy ingot; homogenizing the ingot, cooling the ingot, and then carrying out conventional face-milling on the ingot; coating single-sided or double-sided aluminum-silicon brazing filler metal layer on the ingot so as to form a composite material; heating the composite material; carrying out hot rolling and cold rolling on the heated composite material so as to form a cold rolled material with a first thickness; carrying out complete softening and annealing on the cold rolled material; and carrying out prestretching on obtained sheet after softening and annealing so as to obtain a final aluminum alloy brazing sheet with a second thickness less than the first thickness. A sheet manufactured by using the method disclosed by the invention has more processing combinations, can be processed by using more flexible processes, and can satisfy good formability and brazability.

Description

technical field [0001] The invention relates to an aluminum alloy brazing sheet material, a manufacturing method thereof, and a radiator component manufactured by using the aluminum alloy brazing sheet material. Background technique [0002] At present, aluminum alloy brazing sheets have been widely used to make light-duty brazed heat exchangers. The process can be controlled atmosphere brazing without corrosive flux or vacuum brazing without using flux. [0003] Some radiator parts, such as evaporator sheet, main board, intercooler sheet and oil air conditioner sheet, usually require the sheet itself to have good forming properties to meet the necessary bending, stamping and other forming requirements. In order to obtain this kind of sheet, it is usually required to control the production processes such as homogenization, heating and annealing, so that the sheet has a fine grain structure and high elongation. [0004] This fully softened and annealed sheet will undergo a c...
