Aluminum wiring has several unique traits that its copper counterpart does not. All of these add up to the reason it's no longer used. Aluminum is Soft – When you tighten the set screw down on an outlet or switch, the aluminum wire will actually continue to flatten out a bit over time – even after you stop torquing the screw. This will ...
@Tester101 Wikipedia: Aluminum wire used before the mid-1970s has a coefficient of expansion that varies significantly from the metals common in devices, outlets, switches, and screws. Many terminations of aluminum wire installed in the 1960s and 1970s continue to operate with no problems.
Is aluminum wiring safe? Aluminum wiring is an acceptable wiring choice if properly installed and used in the correct application. Aluminum is a good conductor of electricity. It is light weight, strong and much cheaper than copper. The power supply lines providing power to your home are aluminum as is almost the entire BC Hydro power grid.

Aluminum wires are the color of aluminum and are easily discernible from copper and other metals. Since the early 1970s, wiring-device binding terminals for use with aluminum wire have been marked CO/ALR, which stands for "copper/aluminum revised." Look for the word "aluminum" or the initials "AL" on the plastic wire jacket.

Table of Bare Aluminum Wire. Notes: For the same conductivity aluminum wire is about two gauges larger than copper wire. The table above only lists the AWG standard. The wire size is different between the American Wire Gage [AWG] and the British standard.
Aluminum doesn't conduct electricity as well as copper, so you'll need a larger wire size (i.e. 4/0 for 200 amps, instead of 3/0 copper). But, the cost for aluminum is much lower overall. The main problem with aluminum is surface oxidation when it is exposed to the air.
