摘要： Proposed is a highly corrosion-resistant aluminum alloy including one or more components selected from among 0.1 wt.% or less (except for 0 wt.%) of Cu, 0.15 wt.% or less (except for 0 wt.%) of Si, 0.2 wt.% or less (except for 0 wt.%) of Fe, 0.9 to 1.5 wt.% of Mn, 0.03 to 0.15wt.% of Ti, 0.03 to 0.15 wt.% of Cr, and 0.03 to 0.15 wt.% of Zr, and the remaining proportion of aluminum (Al) and unavoidable impurities. The highly corrosion-resistant aluminum alloy contains Ti, Cr, and Zr in a predetermined weight ratio or in equal weight percentages (wt.%), thereby exhibiting improved corrosion resistance in a saline water environment while exhibiting excellent levels in tensile strength and yield strength.
