Do a web search.

Not as such -- we will probably continue to use 316-SS Swagelok
ball valves as we have in the past. Alloy Al is fine for piping and short
term storage -- it's certainly no worse than 316-SS, according to
discussions Dan and I have had with Nino (the rocket belt guy and the
manufacturer of SMC's special peroxide drums).

Only if the laws of physics are altered to suddenly render
peroxide significantly compressible.
