Flat bar or plate for CNC

[spluppit]

Yes that is correct. 6082 is the general go to material for most general machining, unless otherwise specified or other factors dictate. Its just down to you choosing which sections, bar or plate, tube etc will work for your application as Jazz has explained.

Please be very aware you are paying way way over the odds from the company you mentioned. Many other aluminium or non ferrous suppliers will also cut materials at more competitive rates if cut pieces is what you are after.

I'm sure if you are uncertain of your application the guys here will be happy to advise you.
