319.0

AA 319.0 | Sand or permanent mold 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 319.0 sand/permanent-mold casting wt.% limits agree across Aluminum Association Pink Sheets, St. Paul Foundry and Bridesburg Foundry for eight published elements/residuals. These are three issuer publications of specification limits, not independent chemical assays. Magnesium is deliberately withheld: AA and St. Paul give 0.10 wt.% maximum while Bridesburg prints 0.50. The Bridesburg chart cites ASTM B26-68, but edition lineage alone does not establish which value is applicable; resolve with the issuer or current standard before publication. AA 319.1 is an ingot with distinct Fe and Zn maxima; A319.0 and B319.0 are separate casting grades. Cr is unspecified, not zero; aluminum is remainder, not a calculated bound. F/T5/T6 mechanical, thermal, electrical and fatigue figures require their own matched-condition review and are not averaged.
