The aluminum building wire available these days is different. It’s an AA8000 series alloy vs the AA1350 alloy they used before which caused so many problems. This is required by the NEC, has been for many years now. And if you look at the jacket of any aluminum building wire made in say the last 40 years, it will say right on it that it’s an AA8000 alloy.
AA1350 alloy is what is still used for outdoor aerial power transmission and distribution wire. It works fine for that application.
Around here, your electric range, heat pump air handler, AC condensing unit, the feeder between the meter and load center, among other things, are all commonly wired with aluminum wire and have been for many years. The only time I’ve seen a range wired with copper around here, it was in a house built in the 1960s.
My house was built in 2003 and everything but the main feed is copper, including the dryer and range. Also have all copper pipes but that’s another story. Bottom line? I just don’t trust it.
