Abstract

The composite comprises an al alloy core contg. (in % wt) 0.5-3Mg, 0.3-1Mn, 0.1-0.3Cr, 0.001-0.003Ti, 0.001-0.3Si, 0.001-0.2Fe, 0.001-0.1Cu, 0.001-0.1Zn, bal. Al and an Al alloy cladding metallurgically bonded to >=1 surface of the core, contg. (in % wt.) 0.001-0.1Mg, 0.2-1.5Mn, 0.001-0.1Cr, 0.001-0.03Ti, 0.03-0.3Si, 0.001-0.05Cu, 0.001-0.4Zn, bal. Al. The cladding is pref. 0.001-0.1" thick. The core has high resistance to pitting corrosion and the cladding provides galvanic corrosion protection.
