1.1 This specification covers heat resistant aluminum-zirconium alloy round wire for electrical purposes. There is a family of aluminum-zirconium alloys that are used for heat-resistance (i.e. resist annealing), which differ by zirconium content, tensile strength, electrical conductivity, and maximum use temperature. This standard covers one currently commercially applicable alloy from this family.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
