Aluminum Tubing
Manufacturers & Services

For some reason, a lot of people have been contacting me about sources for aluminum tubing. So, I decided to make a separate page for it.

Strangely, a lot of the inquires occurred during the period following the 9/11 attacks and the scare of countries like Iran and North Korea stepping up their uranium purification process for "peaceful purposes." Right. A certain type of aluminum tube  is used in the centrifuges, so the FBI, CIA, NSA, and all other varieties of 3-letter government organizations began watching the Internet chatter. I actually contacted the FBI about a couple suspicious requests from outside the country. Of course, they never let me know one way or the other whether the leads resulted in any action. Heck, maybe I unknowingly saved the world. You can show your appreciation by supporting my advertisers or even by making a donation to RF Cafe.

NOTICE: Search engines nowadays penalize websites for having many hyperlinks on a web page, so I no longer keep a list of my favorites. Most search engines do a really good job of locating useful data if your search terms are well thought out, so rather than me supposing I know what you are looking for, I have provided this Search box (and one in the upper-left page border) for you to use. If you are interested in advertising, please visit my Advertising information page. Thank you.
