Abstract
The increase in population and your needs it results in a constant increase in the demand for electric energy, requiring the improvement of cables for its transmission and distribution. This work aims to analyze the influence of heat treatment on Al-0,05% Cu-0,27% Fe-0,6% Mg-0,15%Ti base alloy. The alloy was obtained by foundry in mold “U”, the molten material passed through machining and rolling to the diameter of 3.0 mm. After the cold work, some test bodies were preserved without heat treatment, others underwent the heat treatment of aging for 6 hours at 200ºC and the last part was submitted to the thermal resistivity test according to ASTM B941. The structural, electrical and mechanical characterization of the alloy was performed through metallography analysis, electrical conductivity test and tensile test, respectively. All these procedures were performed in order to analyze and compare the structural characteristic, the electrical and mechanical behavior of the alloy before and after the heat treatment and to validate the material as heat-resistant. It was verified that the artificial aging applied for 6 hours to the samples caused a slight increase in the electrical conductivity of the material, but with a reduction of the tensile strength limit.
