Yes, in principle - but the average output power (eg. watts) will be no more than the power the 1.5V cell can provide.
(Rather less, in fact, as the conversion will not be very efficient).
eg. if the cell can give 1A maximum, so times 1.5V = 1.5W maximum, the 230V AC power would be somewhat less than 1.5W
There is always some risk involved when working with high voltages...
Anything below 50V is considered reasonably safe.
Aluminium is rarely used in electronic other than for mechanical parts such as casings and chassis etc.
Copper wire is the normal standard for almost everything.
Silver is occasionally used as its even lower resistance than copper and still conductive if it tarnishes.
It's used for a plating over copper or sometimes as wire.
