AA 1100 | Wrought alloy; Yieh sheet covers sheet and coil

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.

Element / source labelMinimum wt%Upper wt%

Zn—0.1
Others (each)—0.05
Others (total)—0.15

Partial AA 1100 specification limits, wt.%. Six bounds agree in the AA Teal Sheets, United Aluminum manual, and Yieh coil/sheet TDS. These are three issuer publications, not independent chemical assays; United states its composition table is according to AA. The Si+Fe 0.95 maximum is one combined bound, not separate Si and Fe maxima. Al is withheld: AA and United print 99.00 minimum, whereas Yieh's composition table prints 99.10 minimum despite its own introductory prose saying 99.0. Dashes do not establish zero limits for Mg, Cr, or Ti. Physical, thermal, electrical, mechanical, dimensional, and processing tables in the Yieh PDF remain source-scoped discovery pending matched-condition review.

Data under review

Composition Al withheld: AA Teal Sheets and United Aluminum print Al 99.00 min; Yieh composition table prints 99.10 min, while its introductory paragraph says 99.0. The discrepancy is unresolved, so no Al minimum is published.
