Jim,
5052 isn't actually sold in a -T0. It is a different type of material than 6061-T0. 5052 is chemically aged and hardened for sheet metal and is typically fairly soft. It can be purchased annealed, and this would be correct for brake and fuel lines as you mention. I just mention this as a T-0 is a temper designation not normally used on 5052. The common 5052 used for sheet metal is 5052-H32. FWIW

The actual designation is 5052-0.
The -0 is important as it designates the hardness which is very soft (annealed).
Tubing for brake and fuel lines needs to be soft so it can be bent and formed easily.
It's not -T0, Bill, but Jim is on the money with -0. http://www.aircraftspruce.com/catalog/mepages/alumtube_5052.php
I think someone sat down one day and brainstormed up new and impressive ways to make it more confusing.

decisions, but in doing so we actually hurt them (and ourselves)."
