Title
(EN) BRAZING SHEET FOR HEAT EXCHANGER FIN AND MANUFACTURING METHOD THEREFOR
(JA) 熱交換器フィン用ブレージングシート及びその製造方法
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a brazing sheet for heat exchanger fin excellent in all of self corrosion resistance, high temperature buckling resistance and moldability, and a manufacturing method therefor.

SOLUTION: A brazing sheet has a core material and a brazing material laminated on the core material. The core material has a chemical component containing Mn:0.50 to 2.0 mass%, Si:0.050 to 0.60 mass%, Fe:0.050 to 0.70 mass% and the balance Al with inevitable impurities and has a fibrous structure. The brazing material has a chemical component containing Si:6.0 to 13 mass%, Fe:over 0 mass% and 0.80 mass% or less, and the balance Al with inevitable impurities. The brazing sheet has total elongation of 3% or more, local elongation/total elongation of 0.35 to 0.95, and bearing force of 100 to 200 MPa. A metallic structure of the core material has a property to change to a recrystallization structure having average crystal particle diameter of over 200 μm when hold at a temperature of 600°C for 3 min.
