A five layer sheet for vacuum brazing has a core layer of 3XXX aluminum alloy and two interliner layers of 5XXX aluminum alloy bonded to the core layer. Two layers of 4XXX aluminum alloy are bonded to the two interliner layers. An elevated quantity of Mg in the interliner layers can provide enhanced strength, facilitate brazing and provide corrosion protection. A low zinc composition for the sheet also facilitates vacuum brazing. |
