AA 712.0 | Sand casting; 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 ↗

Chemical composition

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

AA 712.0 S casting limits agree in the AA Pink Sheets, Trialco casting-spec column, and St. Paul Foundry table. These are three issuer publications of specification limits, not independent chemical assays. AA Mg footnote 6 exempts Mg decimal places from the general rounding note; it does not change the 0.50-0.65 range. The adjacent 712.2 ingot is a distinct designation; its Si and Fe limits differ. Others-each is withheld because St. Paul omits it. Aluminum remainder is not an inferred bound. Mechanical, physical and thermal properties require separate matched-condition review.
