[QUOTE="SlowSVT, post: 10551478, member: 20202"] There are so many alloys it's hard to say. 356-T6 is a pretty common high strength casting alloy for this application but that is nothing more then a guess. Heating it to 500 degrees may effect the temper and is something I would not do since this is a structural component. We use to stress relieve aluminum at 350 after welding but I would not go higher then that. They are hollow core and appear to be displacement sand castings just looking at the surface finish. I would just press them out and not take a chance melting them out which will be nasty. The sleeves will still have to be removed. [/QUOTE]
