AA 2024 | 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 2024 wt.% composition limits confirmed by BIKAR EN AW-2024 supplier tables and United Aluminum's AA-attributed technical manual. These are three issuer publications of specification limits, not independent chemical measurements. Single numbers are inclusive maxima; unshown minima are unspecified. Al is remainder without an invented numeric limit. AA Teal footnote 7 (printed p. 18 / PDF p. 24) and BIKAR p. 1 permit Zr+Ti maximum 0.20 wt.% only for forged or extruded product by mutual supplier/producer and purchaser agreement; this optional condition is not a general published 2024 limit. Research corrosion data and supplier physical/mechanical values remain unpublished pending separate condition-level review.
