Document Type and Number:
WIPO Patent Application WO/2018/047971
Kind Code:
A1
Abstract:
Provided are: a precoated fin material with which a heat exchanger can be produced, said heat exchanger having superior hydrophilic stability of the fins, superior bonding properties, and enabling bonding between fins and aluminum tubing without separately supplying a brazing material; and a heat exchanger that uses the precoated fin material. A precoated fin material (1) comprising an aluminum alloy sheet (11) and a coating film (12) formed on the surface of the aluminum alloy sheet (11), and a heat exchanger using the precoated fin material (1). The aluminum alloy sheet (11) comprises chemical components that contain 1-5 mass% of Si, with the remainder comprising Al and unavoidable impurities. The Si content in the coating film (12) is 10-300 mg/m2.
