Abstract
Aluminum alloy wires with improved electrical conductivity and improved ultimate tensile strength are disclosed. The aluminum alloys include magnesium, silicon, and copper and are formed without a solution heat treatment. The aluminum alloy wires are useful as conductors for overhead transmission lines. Methods of making the aluminum alloy wires are further disclosed.
Claims20
A process of forming an aluminum alloy wire, the process comprising:
- forming an aluminum alloy rod from an aluminum alloy, the aluminum alloy comprising:
- about 0.6% to about 0.9%, by weight, magnesium;
- about 0.5% to about 0.9%, by weight, silicon;
- about 0.05% to about 1.0%, by weight, copper;
- and
- the balance is aluminum;
- and
- performing a T8 heat treatment or a T9 heat treatment on the aluminum alloy rod to form an aluminum alloy wire in accordance to American National Standard Institute (“ANSI”) Alloy and Temper Designation System for Aluminum H35.1 and H35.1M (2017);
- and
- wherein no solution heat treatment is performed.
