If you are having to buy it talk to your local supplier from memory (and it is very easy to google) 6086 T6 is normal machining grade the suffix indicates the degree of temper (bendability) a T3 spec would be good a bit softer... otherwise I think you would be looking at 6060 in a T6 fairly commonly available. I.ve also thought about milling from billet and instantly dismissed idea on cost grounds but nonetheless an interesting excercise. What mill /control are you using? have you any cadcam and postprocessor software? Are just going for simple profile (2D) with radiused edges.. you may as well buy a decent lump and do multiples / oppsite hands from one plate good luck have fun.
