Abstract
A high strength, corrosion-resistant alloy for brazing is disclosed, which alloy comprises 0.2-1.0 wt % of Cu, 0.1-0.5 wt % of Mg, 0.2-1.0 wt % of Si, and the balance of Al and inevitably present impurities. The weight ratio of Si/Mg is in the range of 1-2.5:1. The alloy may further comprise 0.03-0.5 wt % of Ni and/or one or more of Zr, Cr and Mn each in an amount of 0.05-0.5 wt %.
