[PSUBS-MAILIST] Co2 scrubbers

[River Dolfi via Personal_Submersibles]

A quick search reveals that "Tungum" is an Aluminum-Silicon-Nickel-Brass
alloy that forms a particularly durable protective oxide layer, is extra
corrosion resistant, and can be precipitation hardened like aluminum.

It seems like the best and most expensive option for salt-water exposed
high pressure oxygen components. Probably way overkill for a sub that only
spends a day or two every other month in the water.
