ASTM B531-90(1998)e1

Standard Specification for Aluminum-Alloy 5005 Drawing Stock for Electrical Purposes (Withdrawn 2003)

SCOPE
1.1 This specification covers aluminum-alloy 5005 Drawing stock, 0.375 in. (9.52 mm) in diameter, in the tempers shown in Table 1, for drawing into wire for electrical conductors (Explanatory Notes 1 and 2).  
1.2 The SI values for density and resistivity are regarded as the standard. For all other properties the inch-pound values are to be regarded as standard and the SI units may be approximate.  Note 1-The alloy and temper designations conform to ANSI H35.1. Aluminum-alloy 5005 corresponds to unified numbering system alloy A95005 in accordance with Practice E527.
