Six Industry Standards Receive Updates

ARLINGTON, VA, — The Aluminum Association has released the 2013 editions of The American National Standards (ANSI) H35 on Alloy and Temper Designation Systems and Dimensional Tolerances for Aluminum Mill Products. Updated documents include: 

  • ANSI H35.1/H35.1(M)-2013  - American National Standard Alloy and Temper Designation System for Aluminum was revised from ANSI H35.1/H35.1(M)-2009. This latest revision consists of expanding the wrought alloy designation system and eliminating the requirement that an alloy variation is from another country; addition of a footnote to require individual limits for combination of elements in excess of 0.10%; and addition of a definition for O2 temper designation as a reserved temper to demonstrate response to annealing. 
  • ANSI H35.2-2013 and its Metric counterpart ANSI H35.2(M)-2013- American National Standard Dimensional Tolerances for Aluminum Mill Products, are revisions of ANSI H35.2 and H35.2(M)-2009.  The latest revisions include modification to the column headings for extruded and drawn pipe to harmonize with ANSI/ASME standard; clarifications to tolerance table for drawn tube; and clarification on tolerance calculation for wall thickness (eccentricity) of extruded tube.
  • ANSI H35.3-1997(R2013)-American National Standards Designation System for Aluminum Hardeners, reaffirms ANSI H35.3-1997.
  • ANSI H35.4-2006 (R2013)-American National Standard Designation System for Unalloyed Aluminum, is a reaffirmation of ANSI H35.4-2006.
  • ANSI H35.5-2013, American National Standards Nomenclature System for Aluminum Metal Matrix Composites, is a revision of ANSI H35.5-1993(R2009). 

These American National Standards provide the basis for all U.S. aluminum industry alloys and temper designations, and registrations, and dimensional tolerances for aluminum mill products, a number of which are recognized and used globally. 

The ANSI publications are available for purchase from the Aluminum Association’s online bookstore at
