For pretty much the same reasons, my wife and I love it when our British friend comes to stay with us.

The earliest citation given in the Oxford English Dictionary for any word used as a name for this element is alumium, which British chemist and inventor Humphry Davy employed in 1808 for the metal he was trying to isolate electrolytically from the mineral alumina. The citation is from the journal Philosophical Transactions of the Royal Society of London: “Had I been so fortunate as to have obtained more certain evidences on this subject, and to have procured the metallic substances I was in search of, I should have proposed for them the names of silicium, alumium, zirconium, and glucium.”[64][65]

Davy settled on aluminum by the time he published his 1812 book Chemical Philosophy: “This substance appears to contain a peculiar metal, but as yet Aluminum has not been obtained in a perfectly free state, though alloys of it with other metalline substances have been procured sufficiently distinct to indicate the probable nature of alumina.”[66] But the same year, an anonymous contributor to theQuarterly Review, a British political-literary journal, in a review of Davy’s book, objected to aluminum and proposed the namealuminium, “for so we shall take the liberty of writing the word, in preference to aluminum, which has a less classical sound.”[67]

So the british pronunciation is wrong.
