An extremely careful DD will show there are many BMG's which contain aluminum, there are many BMG's containing magnesium.
Howerver, while there are several aluminum and magnesium alloys, there are no BMG;s to date of aluminum and magnesium BMG's.
In fact it is neither the magnesium or aluminum in any of the formula that makes the alloy a BMG alloy.
While combining magnesium and aluminum do make an alloy, it does not follow that a good BMG will contain both aluminum and magnesium.
This is readily seen by a search of all BMG;s containing Aluminum or Magnesium. You will not find a BMG which contains both.
I welcome further discussion which shows absolutely a BMG including both manesium and aluminum.
Show me the dough and I'll gladly eat crow.
Aluminum corrodes easily; magnesium corrodes easily, it takes more than these two elements alone to make a glass and that was the point I made from the very offset.
A good read on the subject emphasizing the lack of BOTH aluminum AND magnesium in BMG is:
