Wires formed from improved 8000-series aluminum alloy

A building wire formed from an improved 8000-series aluminum alloy comprising, by weight:

• 0.44% to about 0.80% iron;
• about 0.10% to about 0.3% copper;
• about 0.02% to 0.04% silicon;
• and
• about 0.001% to about 0.1% of a rare earth element selected from one or more of erbium, ytterbium, and scandium;
• wherein the improved 8000-series aluminum alloy exhibits an elongation at break of 10% or greater in accordance with ASTM B800-05 (2015);
• wherein the improved 8000-series aluminum alloy exhibits one or more of:
• i) a tensile creep rate of about 1*10−5 s−1 to about 2*10−8 s−1 when measured in accordance to ASTM E139 (2011) at 100° C. with 70 MPa of applied stress;
• and
• ii) a tensile stress relaxation time of about 1,000 seconds or greater to reach about 85% of an initial tensile stress of 75 MPa when measured in accordance to ASTM E328 (2013) at 25° C.;
• and
• wherein the improved 8000-series aluminum alloy is an improved AA8030 aluminum alloy.
