6AL-4V ELI 0.0620" diameter
the spring tension on these are amazing to say the least, I bought $60 worth from

The are a V shape and the ends come out at a right andgle very short ends I will try to snap a pic
I have about 40 cent each in them, make 5 from one stick, they are about 4" long when in the V shape spring, about 4" wide at the base and will be compressed to less than an inch, talk about spring tension, from my dealing with aluminum this stuff is 1000% better for making spring type connections, and cheap from the other places I have seen as well.
I wil get a picture soon
