Aluminiumlegierungslötblech

摘要

There is disclosed an aluminum alloy brazing sheet for constituting a fluid passage, which comprises an Al-Si-series filler alloy clad on one or both surfaces of an aluminum alloy core material comprising 0.3 to 1.5 wt % of Cu and 0.03 to 0.3 wt % of Sn, the balance of the alloy being substantially Al. According to the aluminum alloy brazing sheet, the corrosion resistance can be remarkably improved, and therefore when the aluminum alloy brazing sheet is used for a heat exchanger, the life by the corrosion resistance of the heat exchanger can be improved strikingly, and therefore the industrial effect can be remarkably exhibited.
