Never seen it before. Found the secondary of an old microwave oven transformer was wound with it. The primary was enamelled copper however. I wonder why they used Al.?

Correction - it was the primary, not the secondary, that was Al. Secondary was Cu. Alan
Price?
Could be, although they used Cu for the secondary. I wonder if it's easier to enamel Al as opposed to Cu.

Aluminium is cheaper than copper is my guess.
Some years back I did a modification job on the transformers in some Italian made battery chargers, made for fork lifts, and the transformer secondary windings were insulated (formvar?) aluminium wire.
