ABSTRACT:
A novel aluminum alloy contains vanadium as an alloying element, at a concentration ranging from about 0.02% to about 0.4% by weight. The vanadium imparts corrosion resistance to the alloy, particularly when the alloy is used as a core alloy in a vacuum brazing sheet. A further improvement in corrosion resistance is achieved by processing the alloy or brazing sheet in such a manner that the final processing step is a cold work to a reduction of about 10% to about 20%.
