looking to Identify aluminum alloy
(OP)
I need an aluminum tube with very good reflective properties on the inside. It needs to have a mirror-like finish, but can not have a dark hue to it. The ideal that I have found has a misty type of finish to it. I have no alloy numbers, but I have had hit and miss results with the 3003 and 6061 alloys.
there are usually some suffix after these but I cannot relate them to anything in particular. Any attempts to pollish have resulted in a dark hue and this is an undesirable situation

Come back with a little more information as to the enviroment the tubing will see. Normally 3003 would work fine and can be purchased with a relative smooth inside surface. Any of the 6061 alloys will work but require more effort to polish. The best alloy would be 1100-0 for polishing.
If weight isn’t a problem you can get internally polished Stainless Steel pipe and tube.
