I don't recall ever hearding that one before. For either type of tank.

The horizontal propane tanks I have always used are aluminum, as are my
scuba tanks. And for what it's worth, some of my aluminum propane tanks
are well over 10 years old and have been recertified with no problems.

They make aluminum SCUBA tanks now? I used to dive as a youngster (late
teens) and I remember the dive instructor at the certification school in New
Haven telling us to always store the tanks upright to minimize corrosion of
the side walls. Of course the tanks then were painted mild steel, not
aluminum. In fact, my first regulator was a US Divers two stage, two hose
deal. I really though I was coming up in the world when I got a single hose
regulator.
