Yes, aluminium's tensile strength isn't high enough to suspend its own weight, so a steel-wire core is used.

Its light weight and resistnace to coorsion are important factors. The use worldwide differs. Aluminium alloy, coated aluminium wire are used. In the UK aluminium is not recommended for domestic use.
Overhead transmission lines use steel-cored stranded aluminium conductors. The steel supplies the necessary tensile strength, as aluminium is relatively weak. Copper is not generally used as it is significantly more expensive than aluminium.

Aluminium is used.
Aluminium is better than steel in conducting electricity. Actually, aluminium is one of the main conductors and it is widely used in transmission lines due to its low weight and low cost.
