This specification covers aluminum-alloy T81 round wire which are solution heat-treated, cold worked, and artificially aged for electrical purposes. Following welding, electric-butt welds shall be annealed for a distance of at least 6 in. In order to ensure uniformity in the test method and valid applicability of the test results to the conformance criteria, it is recommended that the rate of separation of the heads of the tensile test machine not exceed 0.
