I was walking home from town today, and passed a skip being used by a sign fitting company

A small sheet of aluminium caught my eye, I grabbed it intending to dremel it for the rear panel on my project.

When I got home I noticed that is wasn't all aluminium, I has a an aluminium face on either side with some kind of plastic/plexi/perspex inside it.

Its very easy to work with, heavy and very solid - this stuff will not bend.  I think it would be great for a control panel.

Anyway - here it is (part worked by me, not complete)

Maybe it's Fire proof Aluminum Composite Panels (Note: They have ---Bad words, bad words, whatcha gonna do? Whatcha gonna do when saint censors you?--- anti-C&P javascript going on there. So I wouldn't bother with their business).

I found it by Googling "plastic core aluminum".

All the suppliers I could find come out of China, Couldn't locate a U.S. supplier.

Many thanks, Your knowledge of scientific biological transmogrifications is only outmatched by your zest for google-fu treachery.

It's probably very toxic and can only be machined while using a gass mask :P
