Twmaster,
Here is some good information for you:
The temper designation system is used to specify the condition, or temper, of a heat treatable alloy. The most common designations include O (sometimes erroneously referred to as TO), F, T4 and T6. O refers to soft or annealed condition and is the preferred temper for forming processes such as tube bending. F refers to the condition of the material following a forming process during which work hardening occurs, and is the official designation of tubing bends. T4 designates that the alloy was solution heat treated and naturally aged. T6 is sometimes referred to as fully "heat treated" and is the result of solution heat treating and artificial aging.
Like I said, look for the "0" temper for bendable tubing!
