I don't know the composition of the metal. The leak is in the impeller housing inlet hose pipe I called the bib. It appears as a pinhole with rust around it (and salt) and drips water which then flows down the impeller outlet hose at the bottom and drips on the floor. Not a great flow but adds up with time running the engine and flows over the galley floor.
Thanks,
