This specification covers aluminium 1350 drawing stock for electrical purposes. The stock shall conform to the chemical composition requirements. The stock shall be uniform in quality and temper and shall be suitable for drawing into wire. The tensile strength tests and requirements for the respective tempers of stock are presented in details. The stock shall be furnished in continuous-length coils without joints, unless otherwise agreed upon between the manufacturer and purchaser. The electrical resistivity tests shall be made on full-section samples of the stock.





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).

(A) Applicable to stock sizes through 0.500-in. (12.70-mm) diameter. The values to apply for larger sizes in these tempers shall be negotiated at time of inquiry.

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 E527.

(A) Analysis shall regularly be made only for the elements specified in this table. If, however, the presence of other elements is suspected or indicated in amounts greater than the specified limits, further analysis shall be made to determine that these elements are not present in amounts in excess of the specified limits.
(A) The equivalent resistivity values for 100 % IACS conductivity were each computed from the fundamental IEC value (1/58  Ω·mm2/m) using conversion factors each accurate to at least seven significant figures. Corresponding values for other conductivities (aluminum) were derived from these by multiplying by the reciprocal of the conductivity ratios accurate to at least seven significant figures.
(A) For this specification, mean diameter is the average of the maximum diameter and the minimum diameter measured in the same transverse plane along the length.
