8.5 pound spool of 0.035" titanium wire

8.5 pound spool of 0.035" titanium wire

I bought this wire a long time ago for a project but didn't need as much as I thought. There is a lot left. The spool and wire weigh about 8.5 pounds. I don't know the weight of an empty spool. Unfortunately I can't remember what grade of titanium this is. I was mainly working with 6AL-4V and some CP. I assume the wire is one of them but I really can't remember.
The inside diameter of the spool is about 9 1/8" and it is 3 1/2" wide. By looking through the sight hole, I can see that there is 5/8" of titanium coiled on the spool.
