The　effects　of　alloying　element　Al　on　microstructure,　tensile　properties　and　aqueous　corrosion　behavior　of　Cantor　alloy　are　investigated.　The　results　show　that　the　crystal　structure　of　Cantor　alloy　does　not　change　with　the　addition　of　6　at.%　Al,　and　the　alloy　still　maintains　a　single　FCC　structure.　The　two　alloys　have　typical　dendritic　morphology　and　obvious　dendritic　segregation.　The　yield　strength　increases　by　24%　and　reaches　219　MPa　without　obvious　deterioration　of　ductility　through　addition　of　Al.　Although　both　Cantor　and　Cantor-Al　alloys　exhibit　pitting　corrosion　in　3.5　wt.%　NaCl　solution　due　to　non-uniform　distribution　of　elements,　addition　of　Al　improves　the　corrosion　resistance　of　Cantor　alloy　through　formation　of　protective　Al2O3　scale.
