I need these all the time and would send similar jobs your way often if you’re interested! I can have metal sent to you if needed.

Discs from 6061 T6 aluminum. 4mm (.16”) thick.
1.) 38mm (1.5”) diameter (quantity 200... listed quantities would be my preference, but can do more or less if easier for you.)
2.) 31.75mm (1.25”) diameter (quantity 250)
3.) 25.4mm (1”) diameter (quantity 150)
4.) 21.59mm (.85”) diameter (quantity 150)

condition of edges is unimportant. I would also be interested in discussing adding a single hole to them. Please leave email address where I can contact you if you are interested in working with me. Thank you!
