Aluminum Chemical Composition

This table contains the chemical composition limits of wrought aluminum alloys in percent by weight maximum unless shown as a range or minimum. Except for “aluminum” and “others, ” analysis normally is made for elements for which specific limits are shown. For purposes of determining conformance to these limits, an observed value or a calculated value obtained from analysis is rounded off to the nearest unit in the last right-hand place of figures used in expressing the specified limit, in accordance with ASTM Recommended Practice E29.
