Disclosed is a method of manufacturing a metallic composite material for use as building material, the metallic composite material including an aluminium core sheet and a titanium clad layer on at least one side of the core sheet. The aluminium core sheet and titanium clad layer are bonded to one another by roll-bonding wherein only the aluminium core sheet prior to roll bonding is preheated to a temperature in the range of 50 to 200째 C. The use of such metallic composite material and to a metallic composite material as such are also disclosed.

The invention claimed is: 1. A method of manufacturing a metallic composite material for use as building material, said metallic composite material comprising an aluminium core sheet and a titanium cladding layer on at least one side of the core sheet, wherein the aluminium core sheet and titanium cladding layer are bonded to one another by roll-bonding wherein only the aluminium core sheet prior to roll bonding is preheated to a temperature in the range of 50 to 200째 C. 2. A method according to claim 1, wherein the aluminium core sheet and titanium cladding layer are bonded to one another by roll-bonding wherein only the aluminium core sheet prior to roll bonding is preheated to a temperature in the range of 110 to 200째 C. 3. A method according to claim 1, wherein the roll-bonding is carried out with a total rolling degree of not more than 50%. 4. A method according to claim 3, wherein the roll-bonding is carried out with a total rolling degree of not more than 45%. 5. A method according to claim 3, wherein the roll-bonding is carried out with a total rolling degree of not more than 40%. 6. A method according to claim 1, wherein the roll-bonding is carried out with a total rolling degree of at least 25%. 7. A method according to claim 6, wherein the roll-bonding is carried out with a total rolling degree of at least 30%. 8. A method according to claim 1, wherein the roll-bonding is carried out in one single rolling step. 9. A method according to claim 1, wherein the method includes pre-treatment of the surface of the titanium cladding layer facing the aluminium core sheet, said pre-treatment comprises the step of brushing of said surface before the bonding step. 10. A method according to claim 9, wherein the pre-treatment is carried out in a substantially dry atmosphere. 11. A method according to claim 9, wherein the pre-treatment is carried out in an inert gas atmosphere. 12. A method according to claim 1, wherein the aluminium core sheet has a composition within a range selected from AA1000, AA6000, or AA3000-series aluminium alloys. 13. A method according to claim 1, wherein the aluminium core sheet is made of an AA3004-series aluminium alloy. 14. A method according to claim 1, wherein the titanium cladding layer has a composition, in weight percent, comprising: Fe 0.35 max. O 0.35 max. N 0.05 max. C 0.06 max. H 0.015% max. impurities each 0.1% max., total 0.4% max., balance titanium. 15. A method according to claim 14, wherein the titanium cladding layer has a composition, in weight percent, comprising Fe of 0.15% max. 16. A method according to claim 14, wherein the titanium cladding layer has a composition, in weight percent, comprising O of 0.12% max. 17. A method according to claim 1, wherein the titanium cladding layer has a composition, in weight percent, consisting of: Fe 0.35 max. O 0.35 max. N 0.05 max. C 0.06 max. H 0.015% max. impurities each 0.1% max., total 0.4% max., balance titanium. 18. A method according to claim 1, wherein said aluminium core sheet has a thickness after roll-bonding in the range of 0.7 to 1.5 mm. 19. A method according to claim 1, wherein said aluminium core sheet has a thickness after roll-bonding in the range of 0.9 to 1.25 mm. 20. A method according to claim 1, wherein one or both of said titanium cladding layer or layers have each a thickness after roll-bonding in the range of 0.05 to 0.4 mm. 21. A method according to claim 1, wherein one or both of said titanium cladding layer or layers have each a thickness after roll-bonding in the range of 0.05 to 0.3 mm. 22. A method according to claim 1, wherein following the roll-bonding of the sheet products into a composite material, the composite material is subjected to a final annealing by holding the composite material for 2 to 16 hours at a temperature in a range of 350 to 550째 C. 23. A method according to claim 1, wherein following the roll-bonding of the sheet products into a composite material, the composite material is subjected to a final annealing by holding the composite material for 2 to 16 hours at a temperature in a range of 400 to 540째 C.
