It is a matter of fact that aluminium wiring for appartements and houses is fine as long as the wires are correctly specified for the load. It works. There are plenty of houses with aluminium wiring that have stood the test of time and plenty more which will.
It's not rocket science. Aluminium is slightly less conductive so you have to make the diameter bigger (and coat it, etc...). When you do that, it is fine.
Aluminium can be and is used in smaller, high power applications, especially when weight is a concern, as it has a higher conductivity per unit mass than copper.
The issue with aluminium wiring in practice is not the aluminium oxidizing. Aluminium oxidisation is self limiting. It is an improper connection leading to a few nanometers of oxidation at the connection site, and thus higher temperature at the site of connection leading to a fire. This is avoidable but some places feel it is easier to ban aluminium wiring than enforce proper electrical connections.
With this logic we could be storing explosives at home, because everything is fine until they explode. Aluminum in house wirings is a ticking bomb, because you just need to make one mistake during connection and this will cause fire in few days, few months or few years.
It's not a ticking time bomb. If you make a grave mistake with bad connections, then it may be an issue. But this is true of all wiring. It's just that aluminium is more sensitive to bad connections.
As long as your electrician uses approved connections and does them to spec, there is no chance of a problem.
It is just wishful thinking that your electrician did not made a single mistake. Assume he did. Then what? You will burn to death at one random night?
Aluminum also expands and contracts much more than copper when it gets hot, so it can just wiggle its way out of any connection. Furthermore aluminum is soft, and if you bend it too much, it will crack or break, so not only connection can get problematic, any corners can get easily problematic as well.
Only madman would get his house installed with aluminum wiring.
