AA 7075 | Wrought alloy; product form and temper not specified for composition

Each value is checked in at least three authoritative issuer publications. Some issuers reproduce a shared standard; these are not independent experiments. Do not use as certified design allowables. View sources ↗

No reviewed mechanical claim for this record.

Chemical composition

Only reviewed weight-percent bounds are listed. A blank bound means only the other threshold was reported.

AA registered 7075 composition limits, wt.%, confirmed by Leichtmetall EN AW-7075 billet and United Aluminum's AA-attributed technical manual. These are three issuer publications of standard limits, not three independent chemical measurements. A single upper number is a maximum; a blank minimum is unspecified. Aluminum is reported as remainder, not an invented numeric limit. AA Teal footnote 10 (printed p. 18 / PDF p. 24) permits Zr+Ti maximum 0.25 wt.% only for extruded or forged products by mutual supplier/producer and purchaser agreement; it is not a general 7075 limit or a published claim here. Mechanical and physical properties remain source-specific and unpublished pending condition-level review.
