I have not had time to really look into it but I did take apart for other hard drives and none of them match what I have I'm not sure where I got it I'm pretty sure it was from a hard drive but I do not think it's aluminum it looks like some form of stainless all I know to do is heated with a torch and see if it melts or glows red I might have to send it off to see exactly what kind of stainless it is
