Does anyone know what the Tuxedo Computers means by their laptops like TUXEDO InfinityBook Pro 16 - Gen7 being made out of plastic but having magnesium alloy steamed onto that? That's what they keep on telling me over email, while on their website it says:

Material: Display lid, top and bottom case made of magnesium alloy (AZ91D), Display frame made of plastic

I am curious....

Then I tell them that Slimbooks are made fully out of aluminium and magnesium alloys, as confirmed by Slimbook, and then they say: We looked at their website and indeed they are made out of "aluminium and magnesium " so they are not metal.

Whatt!?

Aren't aluminium and magnesium metals? What am I missing? So confused....
