So two questions, and I apologize to the OP, because I know this is not discussion you were after, but what is the difference between tube and pipe? also doesn't NRS sell 6063 and 6061?Pipe is measure by I.D. Tube is measured by O.D. Nrs pipe is 6061 and for all practical purposes is not bendable, the anodizing wreaks havok on welds too. If you want something that can be bent get some 6063 instead. Do what you want to with it and then take it to an anodizer.
You may also want to consider powder coating. I don't know what it costs to anodize but I just had pipe powder coated and it looks great and in my opinion it will last longer. As a side note, my new yokes came powder coated from NRS instead of anodized like they used to be.I guess the other option is to get the pipe anodized. Anyone know how much it would ost to have ~50ft of 1.5" sch 40 aluminum anodized in the northern colorado area? Any Suggestions on anodizers?
Maybe if you are an outfitter or you drag your frame across sandpaper.The anodize wears off and still leaves black marks on your boat.
