201.0

AA 201.0 | 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 201.0 sand-casting composition is checked against the AA Pink Sheets, St. Paul Foundry, Meteor Foundry, and Trialco production-spec publications. These are issuer-published specification limits, not independent assays. The Fe maximum is 0.15 wt.% in AA, Meteor, and Trialco; St. Paul prints 0.2 wt.% and is excluded from that claim. The Ag 0.40-1.0 wt.% interval is checked in AA, St. Paul, and Trialco; Meteor has no Ag column. 201.2 is a different ingot designation; other blank elements are unspecified, not zero. Mechanical and physical properties require separate condition-specific review.
