All-aluminum alloy stranded conductors typically utilize aluminum-magnesium-silicon alloys-such as the 6101 and 6201 series-commonly in the T1 or T4 temper. These alloys are based on aluminum with the addition of magnesium and silicon; some variants may also incorporate elements like iron, copper, antimony, or niobium to enhance creep resistance and corrosion resistance.
The CHTA (continuous casting and continuous hot rolling) process is employed to remove non-metallic impurities from the ingots and ensure that magnesium and silicon remain in a solid-solution state, thereby improving the material's properties. Alloy wires processed using this technique can achieve a tensile strength of up to 341 MPa and an electrical conductivity of up to 56.1% IACS.
