AA 520.0 | 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 ↗

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 520.0 casting chemistry is checked against the AA Pink Sheets, St. Paul Foundry, and Trialco production specifications. These are issuer-published limits, not independent assays. The Others (each) limit is withheld pending a third issuer. Adjacent .1/.2 ingot columns are separate grades; blanks are unspecified, not zero. Mechanical, thermal, and physical properties need separate condition-specific review. Only the Mg minimum is supported by all three issuers; its upper bound is withheld pending a third issuer.
