The invention relates to the technical field of aluminum
alloy materials, in particular to an aluminum
alloy material, an aluminum
alloy conductor wire core and a preparation method and application of the aluminum alloy conductor wire core. The aluminum alloy material comprises, by
mass, 0.3%-1.0% of iron (Fe), 0.03%-0.2% of
magnesium (Mg), 0.1%-0.8% of
manganese (Mn), 0.08%-0.3% of
zirconium (Zr), 0.004%-0.03% of
boron (B), 0.015%-0.65% of
rare earth (RE), 0-0.12% of
silicon (Si) and the balance aluminum (Al) and inevitable impurities, the single
impurity is not larger than 0.03%, and the sum of the impurities is not larger than 0.1%. Wherein the
rare earth (RE) is prepared from the following components in percentage by
mass: 0.003 to 0.1 percent of
lanthanum (La), 0.004 to 0.15 percent of
cerium (Ce) and 0.008 to 0.4 percent of
scandium (Sc). The prepared aluminum alloy material has the characteristics of
high conductivity, high strength,
heat resistance,
corrosion resistance and good fracture and
impact toughness, is very suitable for being used as a cable conductor, and is particularly applied to places with high requirements on high temperature, vibration, movement,
corrosion and the like, such as power cables, electrical connecting wires, drag chain cables applied to
metal smelting places and the like.
