Where can I find information on the aluminium alloy and chemical composition?
Any aluminium alloy should be registered internationally and obtain a four-digits number. This registration scheme is supported by so-called Signatories from all over the world and managed by the AA, USA. The EAA is member in this international registration programme. The designation and chemical composition of any registered aluminium alloy is presented in an international registration record also known as “Teal Sheets”. Since the edition 2006, footnote 75 explains the interchangeability of the various prefixes, means, an alloy named AA 6063, AW-6063, A96063 or simply 6063 without prefix is identical. Any other aluminium alloy bearing e.g. a company or brand name, is not internationally acknowledged. Such alloys are not referred to in European Standards either.
