    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.

    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.
