Standard Aluminum Tubing Sizes
These are standard sizes of aluminum 6061-T6 (61S-T6) round aluminum tubing stocked by most aluminum suppliers or distributors in the United States and Canada.

Here is an interesting story for you. Shortly after the Muslim terrorists attacked the United States on September 11, 2001, I began getting a lot of e-mail inquiries into available stocks of thick-walled aluminum tubing. Sure, it seemed strange, but I didn't think much of it. Then, a couple years later, news outlets began reporting increased activity detected by Iran and Iraq related to uranium enrichment using centrifuges. One of the things mentioned was the requirement of specialty aluminum tubing with thick walls. Since inquiries kept coming in, I began checking the IP addresses of the e-mails, and discovered that, indeed, all were originating from the Middle East, Africa, and Asia. I contacted the FBI about it and they sent an agent to my house to investigate. He asked a few questions, took my IP address list, and left. I never heard from him again, but within a couple weeks, no more such requests for aluminum tubing were received. Coincidence?

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
