2050? Aluminum/copper?  

I'm with Stan and would probably use 4140 myself. It worked a treat for me when I made the new ratchet ring for my arbor press - although I used annealed round stock and hardened it myself after machining it. I did make something else from 4140 PH too (chuck keys maybe?) and was surprised at how well it machined even half hardened. Have to say I like the stuff.  

Not Aluminum/Copper, this is some form of tool steel. When I found the info before, it was as hard or harder than 4140. I have a bunch of 4140 1" (and thicker) plate. This stuff came out of a tool and die shop that went under. If I find the specs on it, I'll post them.
