I would like to know what peoples take on transformers windings and what peoples preferences of copper vs aluminium transformer windings been used.

I know what the typical advantages etc. of copper vs aluminium i.e. material losses characteristics, thermal effects, tensile strength, ageing effects, bending flexibility and material sizes etc.

So what i am asking is it a viable value engineering solution to go from a copper wound transformer to an aluminium wound transformer and thus what would be the biggest issue with this?

Would it be the increase in size of the transformer? or the fact that Aluminium transformers are known to have a much reduced life expectancy compared to copper wound transformers or has this issue been much improved with today's technology.

Sorry about the long message.
