Title:

METHOD OF SHORT-TIME BRAZING FOR ALUMINUM ALLOY ASSEMBLY AND LOW TEMPERATURE BRAZING FILLER ALLOY

Document Type and Number:

WIPO Patent Application WO/2001/066295

Kind Code:

A1

Abstract:

A method of short-time brazing for an aluminum alloy assembly, wherein use is made of a brazing filler alloy having a difference between its liquidus line temperature and solidus line temperature of 100°C or less and a maximum temperature in the assembly during brazing is 40°C or more higher than the liquidus line temperature of the brazing filler alloy and 585°C or lower; and a low temperature brazing filler alloy for jointing aluminum alloy materials, which has a chemical composition in wt. %: Si: 4.0 to 8.0 %, Zn: 7.0 to 20.0 %, Cu: 10.0 to 35.0 %, balance: aluminum. The above method allows the decrease of the heating time for brazing and the low temperature brazing filler alloy can be used in a short-time brazing method.
