AA A357.0 S&P casting composition limits agree in the AA Pink Sheets, St. Paul Foundry grade sheet, and Meteor Foundry alloy table. These are three issuer publications of specification limits, not independent chemical assays. 357.0, A357.2 ingot, and B357.0 are distinct. Be and Others-each have only two issuer confirmations; aluminum remainder is non-numeric. No T6 mechanical or physical values inferred.
