Also looking for small cathoes 6inches or less
can't help you with the alu, but with the small cathodes....most places have them in 12 in, 6 in, and 4 in....two places that u can get em good and cheap are http://www.performance-pcs.com/ and http://svc.com/
Try http://www.mcmaster.com . I think they will ship overseas also. Scroll down to the bottom right, under raw materials and you'll see links for expanded metal and perforated materials.
