ASTM B233-97(2003)e1
(Specification)Standard Specification for Aluminum 1350 Drawing Stock for Electrical Purposes
Standard Specification for Aluminum 1350 Drawing Stock for Electrical Purposes
SCOPE
1.1 This specification covers aluminum 1350 drawing stock 0.375 in. (9.52 mm) to 1.000 in. (25.40 mm) in diameter, in the tempers shown in Table 1, for drawing into wire for electrical conductors (Explanatory Note 1 and Note 2).
1.2 The SI values of density and resistivity are to be 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—Prior to 1975, aluminum 1350 was designated as EC aluminum.
Note 2—The aluminum and temper designations conform to ANSI H35.1. Aluminum 1350 corresponds to unified numbering system A91350 in accordance with Practice E 527.
