<p>#CMT# #/CMT# 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. #CMT# : #/CMT# 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. #CMT#USE : #/CMT# Anti-corrosion composite material for the manufacture of pipes transporting hot fluids in e.g. aircraft and vehicles. #CMT#ADVANTAGE : #/CMT# The material combines defined and measurable corrosion characteristics with higher recycling potential than prior art. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-sectional view through a substrate with an anti-corrosion aluminium alloy coating. 1 : Composite material 2 : anti-corrosion layer 3 : substrate material 4 : outer coating.</p> |
