Abstract: Aluminum is widely used in the energy transmission (Tx) and distribution (Dx) sectors due to its high electrical conductivity and lightness. However, pure aluminum has low mechanical strength, which limits its application in conductive cables. The addition of alloying elements, such as nickel, has been an effective strategy to improve mechanical properties without significantly compromising electrical conductivity. This work aimed to characterize and correlate the electrical and mechanical properties of Al-1%Ni and Al-2%Ni alloys, comparing them with commercial alloys already used in the market, such as Electrolytic Conductor Aluminum (Al-EC) and the 6201 alloy. Electrical characterization was performed through electrical resistance tests, while mechanical characterization was obtained through tensile tests. The results showed that the Al-2%Ni alloy presented an electrical conductivity of 64.70 %IACS, higher than the Al-1%Ni alloy (62.95 %IACS) and Al-EC. Additionally, the Al-2%Ni alloy achieved a tensile strength (UTS) of 267.08 MPa, higher than the Al-1%Ni alloy (244.15 MPa) and Al-EC. It is concluded that the addition of up to 2% by weight of nickel is effective in improving the mechanical properties of aluminum without compromising its electrical conductivity, making.
