6201 aluminum alloy is mostly used in electrical conductors for overhead transmission lines due to its excellent mechanical and electrical properties besides to an excellent corrosion resistance. This alloy is heat treatable and the thermal treatment is performed with the objective of obtain the optimal properties for its application. In this work it was studied the effect of different deformation grades, time variation of natural aging as well as the time and temperature of artificial aging on the evolution of mechanical and electrical properties. It was found that solution treated wires at 560°C by 4h, 14 days natural aged, 92% cold deformed and artificial aged at 165°C by 7h, reach a tensile stress of 326 MPa and an electrical conductivity of 57.2%IACS (International Annealed Copper Standard).
