A copper-containing aluminium alloy referenced for aerospace tank applications. The supplied temper and fabrication condition determine how reference data should be used.
Selected reference facts; incomplete alloy coverage. Keep typical values, source minima and composition limits distinct. Reference records are not certificates or design allowables.

Chemical composition
Composition coverage remains pending source review.
Fabrication and material selection
The supplier identifies welding applications, but a finished welded assembly requires its own procedure and property assessment. The chemistry header contains an ambiguous element label, so no composition table is inferred.
Applications and product forms
Confirm the end-use requirements against the supplied material and governing specification.
Standards and acceptance
Identify the governing product specification by the actual form and manufacturing route. A grade designation alone does not establish compliance or equivalence. Confirm the edition, required condition, inspection and dimensional limits through the supplier and an authorized specification.

Technical questions
Are typical values delivery limits?
No. A typical reference value describes the source condition; it is not a guaranteed minimum for a delivered lot.
Which temper and thickness should I compare?
Compare the same material form, temper, thickness/test condition, unit and value basis. Different conditions cannot be silently treated as interchangeable.
Technical sources and verification
Selected reference facts checked 14 October 2026. Source values apply to their stated material condition and are not certification of supplied stock.
