So long as it's not some strange aircraft grade that needs to be stored cold else it hardens, yes sounds good... (You will find out if you try
and bend it)..

Thats not a big sheet, 1200x800, just an offcut from a 4800x2400 sheet which would be around £60 from memory.
You just got scrap value + a bit I recon

I think the film is to minimise the reflection if the sheet is to be laser cut. This film does not mean that the ally itself is a special grade for
laser cutting.
As for it being a special aircraft grade, this is unlikely as laser cut aluminium cannot be used on aircraft due to the affect on material properties
around the cut (laser being a hot process).

I thought the film was to stop it scratching???

Pull some off the plastic off, the grade should be marked on the plate.
The plastic being on does not mean anything, any material can be ordered ex mill with it. As Donut says, it's applied to protect the surface.

You can do it quickly. You can do it cheap. You can do it right. – Pick any two.
