Abstract
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 0.15 wt. % 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.
