Are you sure it's aluminum? That would be highly unusual. It's probably tin plated copper.

Thanks everyone for your input. I am kind of anal when it come to stuff like this.

I looked at the wire closely and it sure looks like aluminum but on the wire I found AWM style 3321 which is tin plated copper so I don't have the problem I thought I had.

The oven is at my home and it is a built in oven. There is a very heavy three conductor wire sticking out of the wall and that is how the old oven has been hooked up for 35 years so I guess going back the same way will be OK now that I know it is not aluminum.

Thanks everyone for taking the time to respond. There is a wealth of knowledge available on the site and you are willing to help. This is why I asked the question here.

The oven came wit an armored pigtail with 12 ga wire and it was not intended to be changed.

Thanks again

Yup, really doubted that any manufacturer would use aluminum wire for that short run. Would be highly unusual to find that since most manufacturers are well aware of the potential issues with interfacing copper with aluminum..

The receptacle/plug method for a built in oven can be a nice upgrade, learned that trick from my Dad. He built his house in the 1950s and was way ahead of his time by putting a plug in receptacles for his built in oven and even separate stove top. Makes it extremely easy if the need arises for servicing or removing them for any reason.

I believe it is code now days to include a servicing switch for the receptacle.. But your option, just trying to make it a bit easier for you down the road.
