multiclad aluminium brazing sheet

The product introduction of multiclad aluminium brazing sheet
A multiclad aluminium brazing sheet for automobile heat exchanger main board, which is composed of AA4045 alloy, AA3003 alloy, and Mod6060 alloy. The above three alloys are produced. The outer layer is AA4045 alloy, and the middle two layers are AA3003. Alloy, the innermost layer is Mod6060 alloy surface cleaned and welded by sub-arc welding, hot rolled, cold rolled, processed to a predetermined thickness of 1.5 to 2.5mm according to the cold working rate of 20% to 30%, recrystallization annealing at this thickness, Annealing temperature is 405℃～415, heat preservation is 2～3 hours, finished products are made by leveling and shearing after being out of the furnace.


 
The function of multiclad aluminium brazing sheet
The multiclad aluminium brazing sheet, which is composed of AA4045 alloy, AA3003 alloy, Mod6060 alloy, which is divided into five layers: the outer layer is AA4045 alloy, the middle layer is AA3003 alloy, the innermost layer is Mod6060 alloy, each of which is alloy The functions are as follows: AA4045 alloy mainly plays the role of welding, AA3003 alloy plays the role of isolation, and Mod6060 alloy plays the role of aging strengthening and strengthening strength and anti-collapse.
 
The Application of multiclad aluminium brazing sheet
The multiclad aluminium brazing sheet is mainly used in the production of automobile radiator heat exchanger motherboard.
