ASTM B221, “Standard Specification for Aluminum and Aluminum-Alloy Extruded Bars, Rods, Wire, Profiles, and Tubes,” has been updated. The new 2014 Edition is available from Document Center Inc. in paper format or for pdf download. It can also be supplied for multi-user access using our Standards Online subscription service. The specification covers aluminum and aluminum alloy extruded bars, rods, wire, profiles and tubes. It is one of our best-selling standards on the subject.
ASTM B221’s 41 different alloys are given chemical composition limits in Table 1. Then Table 2 shows the mechanical property limits of these aluminum alloys and tempers. It’s a comprehensive document, covering the usual scope, referenced standards and terminology. You’ll find clauses for ordering information, materials and manufacture, quality assurance, chemical composition, tensile properties, heat treatment and confirmation of same, reheat treatment, various corrosion resistances, cladding, dimensional tolerances, general and internal quality, inspection, retest and rejection, marking and packaging, and certification.
Mandatory Annexes are also provided. Annex A1 covers the basis for inclusion of property limits. Annex A2 provides a detailed explanation of the acceptance criteria that an aluminum alloy has to meet in order to be included in this document. The non-mandatory Appendix X1 finishes up the specification. It gives you the designations for metals and alloys originally assigned in conformance with ASTM B275.
FYI: I last reviewed this document when the 2012 Edition was released (ASTM B221 2012 Edition is available). This is the second change since that last blog. When the 2012 Edition was updated in 2013, Note 3 was revised. In this new 2014 Edition, changes have been made to Table 2 to match properties listed in the AS&D (Aluminum Standards and Data.) And don’t forget: The metric edition of the document is available as ASTM B221M.
You’ll need a copy of this new edition if you use this specification. Head to the Document Center Inc. webstore at www.document-center.com.
