1.1 This specification covers aluminum 1350-H19 (extra hard) round wire for electrical purposes.

1.2 The values stated in inch-pound or SI units are to be regarded separately as standard. The values in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

1.2.1 For density, resistivity, and temperature, the values stated in SI units are to be regarded as standard.

Note 1 - lPrior to 1975 aluminum 1350 was designated EC aluminum.

Note 2 - The aluminum and temper designations conform to ANSI H35.1/H35.1M. Aluminum 1350 corresponds to UNS A91350 in accordance with Practice E 527.
