Which “Ally”

[Chris R 1Participant @chrisr1]

I want to make some short threaded adapters, up to 52mm diameter, from say 5mm to 50mm long.

I have use of a "Chinese" lathe. The thread pitches are typically 0.5, 0.75 or 1mm pitch. I know it can do 1mm, at least.

I'm assuming I'd best to start with a piece of Al alloy bar.

What material would you advise, and perhaps, where would you look for it other than "Google"? No great strength or other special properties are needed, internally it'll be painted black.

I rather imagine I'll be cutting the threads using more than one pass, and by rotating the chuck manually. The threads only need to be a few mm long, but some are internal.

6082 would be a good all rounder and is what most ME suppliers, metal stockists and e-bayers will be able to supply

6082T6 will suit your adaptors, I did one a few months ago M45 to M71x1

My go to spec of aluminium is 6082T6 unless it is going to be welded then I would use 5083. I also use 5083 for quick and simple jigs if it works out cheaper.
