Material of Expansion Cards

o/

Looking to find out more about the expansion card metal material. It it aluminum?

Thinking of laser etching them to make them stand out a bit more and maybe add some sort of texture to them so I can tell them apart when digging in my bag.

Cheers.

I believe they are aluminum. The texture feels the same between the laptop itself and the cards. They also get much colder than I’d expect plastic to be.

Not the best picture. But, here’s the result. Decided to just make the USB-A card a sacrifice for testing. Looks to be just fine!

Exciting stuff!
