Well I wrestled with this for some time now but I think it is a bit time we discuss Aluminum.

 Since we are exploring everything under the sun now, I have chanced by this on you tube.

 I think this subject should now be discussed as a viable new type of transformer.

 Here it goes.

 Instead of traditional steel we say use the steel Tesla mentions giving to Westinghouse for transformers. It's called Bessemer Steel and was and is the cheapest way to make the best magnetic steel for transformers and Motor generators. But this new steel\Aluminum alloy opens up a new avenue in transformers. One that transforms from voltage to magnetic. Of course the input voltage wouldn't have a direct connection with the magnetic output in theory. Enhancements might include having a high volyage polarizing electric field present while cooling. Sort of an electric magnetic effect. This might optimize the transforming portion of the device to be better able to transform.

 Bessemer steel is the first mass manufacturing process to give us all the steel we see today in the old buildings and super stryctures around the world. Not only was it fine grade steel but it was very flexible to boot. Not as strong as other steels and alloys but steel none the less. Mixing Aluminum with this steel might have some rather interesting effects seeing that the steel is a high oxidant content steel. Aluminum oxide might have some rather interesting properties in this mix.

 The Bessemer process is also the cheapest way to provide mass amounts of steel cheaply even in today's marketplace, yet the process has been shelved. Maybe this is due to Westinghouse buying up a ton of it and they realized they had something and shut it down. Who knows. Can't have a bunch of near unity devices running round can we?

 So what do you think? Don't you think the texture of the material shown in the above video depicts an electrical pattern of discharge? How would steel behave being exposed to the differences between those two materials? Parallel lines indicating an order of some kind, maybe electrical by nature?
