Aluminium can conductive because it has low resistivity which is due to the three delocalized electron present in Aluminium structure. Aluminium cannot be magnetized because it does not exhibit ferro magnetism ( which is the ability of magnet to attract a metal).
Aluminum can be conductive but not magnetized. In fact it has the ability to be a superconductor. But based on the electron spin in the last orbital it makes it Paramagnet. which means that it alone is not magnetic, but it will conform and be attracted to other magnetic fields. note that Al has such a low Paramagnetism that it will not be detectable with out sensitive equipment.
Aluminium saucepans and frypans demonstrate that Al conducts heat, aluminium wires are used because it is a very good conductor of electricity, but lighter and cheaper than copper, so used on overhead cables. Most lay-people would describe Al as non-magnetic. However, Al is weakly paramagnetic. It does not hold a magnetic field, but does respond to a (strong) magnetic field, albeit weakly. The effect is strongest at low temperatures, and decreases as temp increases.
Aluminum is conductive. In fact at one point in time it was used as an alternative to copper wiring for home electrical wiring. (There were problems, so it is no longer used).
