A study has been made of the various alloys for body sheet. These include the non-heat-treatable Al-Mg alloys and heat-treatable alloys of the Al-Mg-Si and Al-Cu-Mg types. Tests have shown that each alloy has a different combination of properties with no alloy excelling in all characteristics. At this stage in the development of aluminum body sheet, it would appear that the Al-Cu-Mg alloys 2036 and X5020 should be preferred over other types for general body sheet application. Where Lueder bands can be tolerated, Al-Mg alloys such as 5182 and X5085 offer an advantage of superior formability and are recommended for use as inner stiffening panels and supports.
