Engineer Dario Panetta analyzed the ingots from the wreck via X-ray fluorescence and found that they are made up of 75 to 80 percent copper and 15 to 20 percent of zinc with traces of other metals including nickel, lead and iron.
Retired physics professor Enrico Mattievich disagrees that these ingots represent orichalcum, which wasn’t brass-like at all, he says.
“It appears they are lumps of latone metal, an alloy of copper, zinc and lead,” said Mattievich.
