Shiny <-> not shiny is probably just a result of the surface and its structure.
It is impossible to tell which elements are in those objects just by looking at them, but you can find out which materials are frequently used for those objects.

I do not need this kind of answer.

Like I asking "what kind of of tree is that?", then your answer is "It's green".

but you can find out which materials are frequently used for those objects.

Where?

I see a different comparison:
"What kind of tree is that?"
"It is not a tree, it is a house."
Where?
In >100 books and web pages about rims.
Wikipedia is a good place to start

Obviously, someone sells these items. Start with them. Do a little digging, find out who makes them. They certainly should know.

My guess: Aluminum. The shinier ones will have chrome applied to the exterior.

There is a reason that the nickname for alloy wheels is 'mags'. They were originally made largely of magnesium alloys. Due to durability and maintenance issues, magnesium fell out of favor and was replaced by other alloys, mainly aluminum. The shiniest ones are indeed chromed, that is, plated with chromium.
