Yes, this is 5005 H32 Alloy

Did you mean 5052 H32? Do you know the diameter, thickness, and RPM? @@battynz

@@customflightltd4180 No, it's 5005, Diameter is 590mm and 0.9mm thick. Approx 600RPM

@@customflightltd4180 Are you a metal spinner or want to spin this on a lathe, cause I can tell you that this is one of the more difficult spins to produce. It's not for beginners.

Thank you for the info Patrick. I have spun a few things over the past 10 years, the biggest so far being 8" dia. I want to spin a 40" dia. 10" deep engine cowl nose bowl. I am building a custom, big, spinning lathe. I know there will be a steep learning curve going from 8" to 40" , but it's not my first machine build and I don't give up.@@battynz
