Standard Specification for Aluminum 1350 Drawing Stock for Electrical Purposes

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).

TABLE 1 Tensile Property Limits^A

Temper	Tensile Strength
Temper	ksi	MPa
1350-O	8.5???14.0	59???97
1350-H12 and -H22	12.0???17.0	83???117
1350-H14 and -H24	15.0???20.0^A	103???138
1350-H16 and -H26	17.0???22.0^A	117???152

^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.

TABLE 2 Chemical Requirements^A

Element	Composition, %
Silicon, max	0.10
Iron, max	0.40
Copper, max	0.05
Manganese, max	0.01
Chromium, max	0.01
Zinc, max	0.05
Boron, max	0.05
Gallium, max	0.03
Vanadium plus titanium, total, max	0.02
Other elements, each, max	0.03
Other elements, total, max	0.10
Aluminum, min	99.50

^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.

TABLE 3 Electrical Resistivity Limits

Temper	Resistivity, ???? mm²/m, max	Equivalent Volume Conductivity, % IACS, min
1350-O	0.027899	61.8
1350-H12 and -H22	0.028035	61.5
1350-H14 and -H24	0.028080	61.4
1350-H16 and -H26	0.028126	61.3

TABLE 4 Equivalent Resistivity Values at 20??C^A

Material	Volume Conductivity, % IACS	Resistivity Constants
		Volume
		????mm²/m	????cmil/ft	??????in.	??????cm
Copper	100	0.017241	10.371	0.67879	1.7241

Aluminum	61.3	0.028126	16.919	1.1073	2.8126
	61.4	0.028080	16.891	1.1055	2.8080
	61.5	0.028035	16.864	1.1037	2.8035
	61.8	0.027899	16.782	1.0984	2.7899

^A The equivalent resistivity values for 100 % IACS conductivity were each computed from the fundamental IEC value (¹/₅₈ ????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.

TABLE 5 Diameter Tolerances

Specified Diameter, in. (mm)	Tolerance, in. (mm), Plus or Minus
Specified Diameter, in. (mm)	Deviation of Mean^A Diameter from Specified Diameter	Deviation at Any Point from Specified Diameter
0.375???0.500 (9.52???12.70) 0.501???1.00 (12.73???25.40)	0.020 (0.51) 0.025 (0.64)	0.030 (0.76) 0.035 (0.89)

^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.
