Doesn't the mention of titanium here seem wrong? If the Electra had been built of other metals, say aluminum and titanium, there wouldn’t be anything left but free atoms floating around. Titanium is supposed to be resistant to corrosion in seawater due to the oxide layer that forms: https://journals.sagepub.com/doi/full/10.5301/jabfm.5000387 https://journals.sagepub.com/doi/full/10.5301/jabfm.5000387 Titanium is reported to be highly resistant to general corrosion in seawater. ... These properties make titanium suitable for a variety of applications involving seawater, starting from thin-walled heat exchanger tubing, with consequent good heat transfer properties, up to submarine hulls, ships, platforms, desalination plants, salt production evaporators and water jet propulsion systems.
