Structural entity for the tattoo resembling spine surgery involving 6AL-4V ELI alloy

I have very little background in chemistry, so forgive me if I sound ridiculous and uneducated.


I want to have a tattoo designed in honor if my spine surgery that I had. I think that molecular structures (I think that's what its called -- the hexagonal structure stuff?) look pretty cool and I'd like to look into getting something like that. 


Anyways, I dug some stuff up and came up with the alloy that orthopedic implants are usually made of, [6AL-4V ELI](https://en.wikipedia.org/wiki/Ti-6Al-4V). Now, this is where I get stupid. Do alloys have molecular compositions at all? And if so, what would this one look like? 
If I just sound dumb right now and there is none, is there an alternative structure that could be used? 


Again, I'm sorry if this is a silly question and is just wasting time, but this surgery is something I'm really passionate about and I would really like to have something visual to represent it by.
