help please- data analysis

Showing 1 to 1 of 1

Metal                                                Aluminium

 1. Density =                                          3

In g/cmᵌ

2. Relative electrical conductivity =          38

3. Melting point in   ͦc =                      660

4. Relative thermal conductivity =          237

This was meant to be a table but it didn't work anyway can you tell me properties from the results that whould say that aluminium is the best metal to use for a overhead power cable. 

Thanks a lot. nd if you don't understand anything please  ask. :)
