To the OP, Wearymicrobe:
What is the part number on the faces?
I see 021XXXX
The number after 02 is the model name. Usually.
As far as Mg vs Al - I am fairly certain it is MG.
To test, pull the wheel off, put a drop of vinegar on bare metal(backpad or lug nut area). Aluminum will not react in any visible way. Magnesium will.
