I'm trying to create a better anodized aluminum material for use with objects/electronics (such as Apple products) as well as architectural components such as aluminum window mullions. This is my progress so far.

It looks awesome!
I am not sure if it exists in real life references of this material, but for extra realism, especially in the close-ups, you could try adding a layer of thin film manually or using this plugin https://www.sigershop.eu/free-3ds-max-plugins/sigertexmaps-thinfilm/

Are you referring to mimicking a thin layer of finish on the outside of the aluminum?
-
I mean a very thin layer of rainbowy film, when you see something really up close. I am just not sure if this effect appears on metals.

I've noticed looking at many metal samples (mainly silver color) in the office that there is a layer that appears as a mix of green/purple at certain angles (unless it isn't an additional finish but just a characteristic of the specular reflection itself).
That micro specular color varies for other colored metals.

Could be several things: some sort of subtle tarnishing or oxidisation / oil from hands that then gets imperfectly cleaned off / OR probably a type of lacquer/varnish of which there are many types and thicknesses.
There is even a type of lacquer that is marketed as 'nano coat', several companies do a version of it, that is suposedly invisible and completely protective, but in our experience does produce some very subtle oily-rainbow type effects in places.

I think it looks great, good job +1
Also, Maru, thank you for sharing the siger texmap, I've never seen it before

I know this is an old thread, but with regard to aluminum, there is in fact a thin film of aluminum oxide that forms over the aluminum. This is why cutting aluminum foil with scissors can actually sharpen them.
Aluminum oxide is corundum, btw, a very hard mineral with a Mohs hardness of 9 (diamond is 10).

Op, did you make this material public anywhere?
I'd love to learn from how it was made.
