Corvette magnesium engine cradle corrosion study

Possibly relevant — automotive magnesium (15–20 lb/vehicle) placed under the dashboard where white rust is hidden. Not named explicitly; tagged speculatively.

Helicopters often use cast aluminum, cast magnesium parts. Today in automobiles there's about 15 or 20 pounds of magnesium in an automobile, mostly underneath the dashboard where it's protected from any road salt or anything like that. So it's basically in the occupant compartment, underneath the dashboard, so if it does start to show white rust, people don't see it. They also use magnesium sheet in some applications. So castings or sheet metal.
