A composite material (1) has a substrate layer (3) with a full or partial anti-corrosive coating (2) of aluminium alloy. The aluminium alloy additives represent or are less than by percentage wt.: Mn, 1.8; Zn, 0.05; Cu, 0.05; Si, 1.0; Cr, 0.25; Zr, 0.25, and Mg, 0.10. The residue is aluminium and unavoidable impurities each representing no more than 0.05 per cent Wt. and in their sum no more than 0.15 percent wt. The anti-corrosion layer represents 1.2 to 1.8 percent Wt. Further claimed is a process for the manufacture of the composite material. |
