Document Type and Number:
WIPO Patent Application WO/2014/112636
Kind Code:
A1
Abstract:
Provided is an aluminum alloy wire which satisfies all the requirements necessary as a thin conductor for an automotive wire, namely, sufficient strength, sufficient elongation and sufficient conductivity. An aluminum alloy wire in which: the magnesium atomic content (M) (at%) and the silicon (Si) atomic content (S) (at%) fall respectively within the ranges represented by formulae (1) and (2) with the balance being composed of aluminum and unavoidable impurities; the mean grain size in the metallographic structure observed in a cross section is 3 to 20μm; the precipitate size in the metallographic structure observed in the cross the section is 100nm or less; and the number density of precipitates in the cross section is 1/μm2 or more.
[Numerical formula 1]
0.2 ≤ M ≤ 1.19 ··· (1)
-0.81M + 1.44 ≤ S ≤ -1.54M + 2.31 ··· (2)
